what's causing this? it's pretty suspicious especially when you're in a thread with no obvious video posts or anything
I think it's normally an mp3 embedding bit or something from a link.
It's flash but I guess a part most people don't have installed any more maybe?
This just happened to me on Chrome where Flash is built in (though I have it disabled by default).
It happened on this thread
I just disabled all downloads from community.drownedinsound.com.
