this is against the rules
u wot
4chan only has a couple boards that are okay, otherwise dont really browse there.
I'm not trying to advertise but there's this really neat community where they test malware and stuff, you have to apply to be able to download the attached files for testing so it isn't risky. They don't really allow any attachment downloads in the Testing Board, because of the risks there could be.
http://malwareup.org/It's a really nice community and they're pretty mature people. I've been there for about a year and I talk to people sometimes on the chat. It's pretty quiet, a few people ranging from 30-50 are online at a time. The most you'd ever see is around 100-150. It's not as huge as Blockland Forum's is.
