Seems moderators removed all spam by newbie. Its pretty clear that they have created few account just for bump their ANN thread. I know it's not appropriate to ban or nuke just for single mistake but sometimes moderators should consider few accounts why they have been created. At least temp ban like a week would be appropriate. So they will not able to spam instantly.
However, thanks to moderators whoever clean whole spam from the ANN thread. This is the lesson for spammer and project management as well.
Most of the accounts were nuked as all of their replies were posting the same "great project" nonsense. A few of them accounts only had their posts deleted, but most of them were nuked. Temp bans are good, but considering moderators can't issue those, and only global moderators plus can I'm afraid the amount of these types of reports will likely be too much. So if they're obvious cases they'll likely be nuked instead.
