I've got Bitcoin Discussion on ignore, so I wouldn't have noticed any increased spam there, but I haven't really seen it in Reputation either. But if you see spammy shitposts, just report them wherever they are. The mods will take care of it.
Also, my guess is that people are discovering bitcointalk right now because of the price rise. That still doesn't explain the spam, but it would account for more shitposts from bounty hunters and the like.
