Some other members have been given spam cleanup powers though, like Someone Else.
Minor problem: I live in the Americas, too. I'm apparently asleep when most of this has been happening, although I have hammered a few of the Chinese bots.
Just have no links in the first posts then?
This is indeed already in place, although it's apparently not entirely reliable, since it can be worked around by posting a link-free post then editing in a link.
When a new user posts a post with a link, it goes into a hidden buffer called the "moderation queue," where the mods can then approve it or see that it's spam and ban the bot. I've heard that captainnana has been working on opening this up to the spam cleaners (such as myself and Pyure) as well, although this doesn't seem to be working yet- at least, I haven't seen the queue pop up when I'm logged in.
Perhaps a temporary fix could be to adjust the filter so that posts with funky Unicode go in the queue as well. Once again, the post-some-text-then-edit workaround is still there, but I assume that'll be fixed by applying the filter to edits as well.
Perhaps, step 1 should be a class of poster who can report without a cool down.
Step 2, more spam hunter level people, pick from those in the previous step who did a good job reporting.
I've taken to reporting the entire profile when it's a new spambot
I like this idea. Maybe there could be a point system, where users gain points by reporting posts that later get spam-cleanered, and after reporting enough spambots this way, the cooldown starts to decrease. I *think* that the best way to get the mods to notice that you're good at reporting spambots is to report lots and lots of spambots, which people don't want to do because the cooldown is obnoxious. Removing it entirely opens the door for people to spam-report stuff, which is a pain for the moderators (actual mods, that is- I don't have access to reports). However, reducing the cooldown for more trusted users would start to break down that barrier.
