Currently 99% of the spambots are blocked, but still there are quite a few that get through.
I'm working on eradicating the bots, but it may take some time.
In the meanwhile, if you see a new post from a new user, please do a search on Google for a sentence from the post enclosed in double quotes before replying.
If there's already an existing post with the same content, please post a reply that it's a spambot, and report it.
Thanks
