It would seem that the Kitten’s Comment Pay extension I installed has put an end to the comment spam for now. The spammer in question didn’t choose to pay me to post his/her spam, rather he/she got frustrated that his/her posts were not showing up and all they got was a screen asking to send me money.
To you, dear spammer, I say, “I find your lack of faith disturbing“.
Ah, the irony.
You spamma me, I charga you money.
