RMT

[Taliriah]

It's simple to adapt the regex to match new RMT string permutations. All SE has to do is make it a plain old text file that's read by the server every few minutes to keep the regex fresh and up to date.

And it's even simpler for the spammers to create new string permutations, as well as to create new domains for their site.

Also a hearty lol at the idea of updating a regex operating on the chat in real time directly on the live game. Yeah, let's make it both possible and likely to break the game's chat at any time! Especially since regexs are so notoriously easy to get right on the first try.

Let me guess, you work in web development?
