We've recently been plagued by several incarnations of a "ccdeal" user, and it's been quite annoying. Not the first time we've had a spammer create new user IDs by just changing the number at the end, and it won't be the last.
Catchfire and I try to catch as much as possible, but overnight and early morning spam is the norm. Yes, even us superheroes of moderation must sleep, tend children, etc. We ban them when we see them. If we had the capability, we'd block by IP address.
Thank you all who flag spam. It makes the job of overseeing such a large discussion forum easier.
