Recorded for my own reference:
User "pele21091" created a spam post on 17:43, 29. Jul, 2015. I deleted it.
I doubt the user will return, given the nature of false accounts for spamming. They'd be more likely to create another new account.
"pele21091" can be purged from the system. We might consider employing a method to make it more difficult for bots to create an account. Or not, since we're such a small operation and this is likely to remain a rare occurrence.
