Hello, @zac, and welcome to TootCat! Sorry about the spammy mess; this is our first bot invasion since I took over as sysop in January.
I've suspended all the ones that had actually posted any spam, and I'm silencing the ones that fall into the same pattern but haven't posted anything yet. Please feel free to report any others you spot (or @-mention me if you have any questions/concerns).
Thanks!
