Blacklisted on ExpressionEngine?

I tried to register on some expression engine forums.
From the start it said that one of my domains was blacklisted. I don't know how becauze I have never used this platform yet.

After a while it also said that my main domain is blacklisted too.
How do these blacklists work? Is there any way to remove my domains from their blacklist? Do they have something to do with Akismet or is this a different protection system?

Any advice?

The Low NoSpam ExpressionEngine addon supports both Akismet and TypePad AntiSpam.
