It's nice to see spammers are putting so much effort into this. I guess this is what we call an excess of form.

Note to spammers: It's easier to simply make good posts

I suspect someone is using a bot of some sort to search for posts, and change what they say. I wouldn't be surprised if the spammer doesn't do anything himself after the bot is setup, and account created.
The merit system should do a pretty good job of combating this because these guys probably will not get sufficient merit
