This is a great idea to fight spambots.

Using the default "activation" link as the "delete this" link that comes first, while using a different URL to actually activate.

I mean it'd only work until some human caught on and changed the scripts they're selling, but then it could be changed again.

I would get my account deleted so many times then.... I just blind click the first link in that mail everytime, too lazy to read.
If they do this, they better send a big message to me first!

I'm sure spambots are learning.
If they see that validating the first link doesn't grant them access to the forum, they will register again and try the second link.
