I've left a message on the anon's talk page, and while it's a bit unclear at the moment, they SEEM to be making an attempt at correcting their edits. The problem with that is all of their attempts at fixes are listed by them as "Fixed typos", which could mean anything from actual corrections to removing {{context}} templates on unclear examples which, as I noted in my summaries, are basically reminders to add the ages of the characters (and thus clarify that they are indeed proper examples).

Yeah, I just saw your messages, and added one of my own. A lot of his examples are also not quite right for the page, I realize, and ought to go places like Precocious Crush. I am debating semiprotecting the page so that only logged-in users can edit it, to slow him down a bit while we fix what he's doing.
Right, so update on that - this anon is making edits to other pages, and they're starting to get worse. There's been cases such as this where I'd swear they only read as far as the title. I've taken the time to inform them on the most recent address they used, and I was wondering if you could possibly tip them off at their other IPs and/or do something to get their attention or correct their methods somehow.
We've tried to get their attention before, to no avail. I think we're going to have to start playing whack-a-mole with their IPs.

Yeah, I was hoping we wouldn't have to jump to page protection or any other administrative action YET, but I'm not seeing much other choice.
UPDATE: They're back again, and I don't think they've learned anything.
I hate to be That Guy with the Banhammer, but if they're not contributing meaningfully, and they're not responding to any communications, all we can do is play whack-a-mole with them.
Speaking of which, they appear to be back, coming from IP 139.80.239.132 now.

Do what you need to do, LT.
I believe LulzKiller already did it.
