lol, blacklist sbb links then xD

I don't feel like writing extra code. I mean it's fine to post links to other forums but don't misuse the service by mass creating links

I'm not entirely sure why this bothers you? It's a URL shortener. Additionally it would take maybe one or two lines to add a whitelist in the file. If you want to go down the more manageable route store it in the db and then it's maybe 10 lines extra.

Not even that, really. You can 1 line a regex match and an if-condition. This is one lazy ass developer. Yes, I'm being a bit rude to Icy, but honestly, if you're too lazy for a simple blacklist, even for one URL, then why are you even developing a URL shortener?

Exactly.

I wouldn't be surprised if he found a URL shortener online and used it. It's not difficult to create a blacklist nor is it time consuming.
