Because I've removed the new, impossibly difficult human-verification system from Thutopia, I am getting spam. For that reason, I'll be deleting spam.
This may not blow your mind or anything, but I've never deleted spam. I've never gotten that much and it's all in there somewhere.
I reserve the right to leave spam that strikes me as worth preserving, but no longer will I keep all spam as a fun snapshot what ejerks were up to.
That is all.
postscript: so far blogger's deleted them all without my input, so removing the captchas has not actually resulted in any more work for me anyway---except in writing posts on the subject
