Greetings.
We have undergone a rash of spambots lately, and as a result will be instituting new measures to help curb the tide.
Most immediately I will be doing a regular prune of users.
If you have not posted within a week of registering an account, it will be automatically deleted. Many of the bots currently causing us issues mass register and then sit on a timer, or look for specific content to post against, then activate.
