It's not a troll, it's a spammer. They do some test edits that don't contain URLs, which are accepted; then they try to post their spam links. The spam links get rejected by the anti-spam stuff I put in, but the junk/test edits do succeed. Perhaps I should just remove the ability to edit cards anywhere if not signed in.

"Perhaps I should just remove the ability to edit cards anywhere if not signed in."

That's probably worthwhile. Even if anyone can sign up. I think comments and browsing by anonymous users is probably important, but I don't think I've seen anyone want to edit a card who wasn't already sufficiently committed to sign in.

Triple that notion. I have yet to get anything close to valuable input from someone who isn't logged in. I don't think we'd be missing much.

Okay. The cardset option to allow edits by non-signed-in users will disappear in the next update.

Although, doh, I'd forgotten it was already an option -- probably most cardsets should have already been "edit by signed in users anyway" so it shouldn't make much difference to make it impossible, although on balance, I agree removing the option (or at least, making it clear it's a bad idea) is worthwhile.

Jack V, this is completely random, but have you ever read anything by K. J. Parker?

LOL. No, but it looks interesting now I google it. WHy doyou ask?

He (or she, no one knows) has a fondness for the term "on balance," which you also use. Just a tiny connection. lol
