There's a spambot posting in the G&T forum.
I opened his three (so far) threads, and reported each of them as "Spam," "Spam," and "Moar spam," respectively.
Upon attempting to submit the last one, I got a pop-up saying that I had posted 2 times withing 60s, and therefore a spam blocker was now in use against my account, and that I had to wait for at least 60s to post again.
1) Is that permanent?
2) I didn't actually post anything; I reported a post for spam, so I'm not sure why a "posting too often" tool was employed. (Probably reporting a post is treated, in some ways, like making a new post.)
