I highly recommend using cloudflare's csam scanning tool to stop illegal images from appearing on your site. It also helps to block proxies as well. I think as an imageboard community we can stop this shit but we need to start taking measures to put an end to it. If you want to step away from your board for awhile don't leave posting open. It will get spammed. Just put it in read only until you come back.

And yes, I'm posting this on all the imageboards I find. No I'm not a bot.

1. It didn't exists when I started using the current solution
2. As far as I know it can only match for an exact fuzzy hash which kinda defeats the purpose, small differences are the same. I think this helped catch me CP images which were the same but with a different URL watermark.

Fair point, you've been on jschan longer than I have. With jschan's implementation it takes some massaging to match nearly identical images, but it doesn't just match the exact file. For example, here are two hashes from spam posts:
ff00c1d57a61a8ba
ff00c1d57a61e8b8
All I have to do is filter for ff00c1d57a61a and ff00c1d57a61e to stop future spam for that specific image, variants included. Sounds like your implementation is more finely tuned, though.

Since we're on the topic of spam, I'll shill XJ-9K to you:

I haven't implemented anything from them yet but it is a pretty neat project.

Feels pretty tedious. If you calculate the hamming distance between the two hashes, you'll see that's 2. If jschan could do it, you could just add a filter for ff00c1d57a61a8ba and (say) max distance=2, and it would match both. And also ff00c1d57a61acbe, which is also bound to be similar.

My "hashes" look like this:

I should have given ff00c1d57a21e8ba as a second example, because what I gave is also matched by your filter.

It hasn't been too tedious on my end, but I've been stopping them in other ways that involve less whack-a-mole. I'll have to peek at your source code and see if your method works for me sometime. With regards to imagemagick, GraphicsMagick just werks for me, your mileage may vary.

/animu/ has been requesting a news board in their meta thread and it seems like some anons are upset with anoncafe's /k/ along with /tv/ being used for news. When I asked loleron he responded with a(n understandable) strong no. I believe a news board would be a headache for any site due to its implications, but in the interest of anons repeatedly bringing it up after being shot down, I would like to request a /news/ board I can moderate here on trashchan. If it's a hard no, I fully understand why, and I don't hold that against you. As stated elsewhere, it will be advertised as existing if made.

Reposting the board application I used on PLW:
Email: takenbake at protonmail
Name: /n/ (or /happening/ or /news/) 
Description: IT'S HAPPENING (or just "Journalism & News")
Default anon name: /n/ewsman (or /news/man)
Tags: Journalism, News, HAPPENING, Recent Events
Rules:
>1) Board is for Journalism & News - Thread OPs must either be news or personal investigative journalism into a topic. [1]
>2) Pundits are journalists.
>3) Moderation reserves the right to ban troublemakers.
>4) No Doxxing. Publicly available information is not doxxing. State your sources when using publicly available information to avoid an accidental ban.
>5) No schizos.

Generally the lolcow sorts. You know them when you see them.

That's fine, figured I'd ask. I'm not particularly attached to the idea.
>or as nu/pol/.
Yes that's my primary concern and why I'm not pursuing this very hard. Unfortunately it would almost certainly end up with that sort of reputation as a news aggregate board, but trying to police politics would make the place too much work.
>Also, by advertising you mean this?
Yes.
>I'm a gatekeeper type, I've seen too many things ruined by the hordes of normalfags.
I'm more of the "live and let live" sort but your concerns are understandable.
Thanks for the fast response.

I'm one of the other anons from the aforementioned threads
While I see where you're coming from with this decision, I'd also like to see some more boards in general on the webring, especially for topics that aren't already being discussed on a specific board. Frankly, it's kind of bothersome that the only few places to talk about current world events is a couple of threads on a gun's and gun'sbrasters board and on an alternative anime board.
As >>24 states I am also fearful of the possibility of attracting /pol/shit or /leftypol/shit, but it's practically part and parcel of dealing with world news. If anything, a moderately populated discussion board is much more defensible from their kind, as the amount of posters that don't fall for niggerpill is significantly higher in places that let them speak more freely.

Speaking of, how is a board that is being held beck by gatekeeping practices supposed to grow in size? I hope I am not coming off as uncouth, I'm just curious about how it can get an userbase by means other than advertising it in the right locations.

>but trying to police politics would make the place too much work.
Also, if you police not enough, anons will be butthurt about why don't you remove that, if you police too much, they will be butthurt about that. Add any kind of /pol/ content, and you just made the problem 1000 times worse. Finding a balance requires a lot of work, if it's possible at all, so if you're not ready for that, it's probably better if we don't have this board.
>I'm more of the "live and let live" sort
I'm too, as long as they're outside and don't bother me. The problem is that they're usually not that kind, so if you let them in, they'll immediately start to force their ideas on you. Also pic related.

>a moderately populated discussion board is much more defensible from their kind
The less populated the board, the more defensible is, because /cow/tard attention whores generally ignore them. If you want to do this on a board with more than two anons, you need rock solid moderation to remove any derailing /pol/shit attempts on sight, but at that point you're dangerously in rulecucking waters.

It links to http://trashchan2rvdng5zm7346sfxrrkjwvqzolw4lfdyldcsdpmsyj4dkid.onion/ which just says "Go away" when it should link to http://trashchan2rvdng5zm7346sfxrrkjwvqzolw4lfdyldcsdpmsyj4dkid.onion/index.html
So does the other frontend links, but it should be fixed now.
Would you guys like to be friends with kind.moe? As you can see, we're already both part of the webring but also have a dedicated affiliates page.

Um, we don't have any dedicated affiliates page, and I suck at finding friends to warrant a dedicated page.
