Wow real nice Paradox pulling and talking about it would be a ban.

Note Paradox' statement in the /r/Stellaris thread:
We saw the mod, thought it wasn't in very good taste, but let it remain. Then the creator of the mod decided to update the description of the mod to promote an "agenda" not related to computer games at all, and this was being clearly displayed on our product page. We decided it was a step too far and removed it. Eurogamer did not do a good job describing what exactly it was we removed.
Edit: Twitter statement.
We have a few rules of conduct that have been in effect for the better part of a decade where racial slurs, among other things, are not allowed. We interpreted this particular mod as breaking those rules of conduct, however it would appear that the comments surrounding the mod, rather than the mod itself, were the biggest problem.
We welcome everyone to create all kind of mods for us as long as they comply with our rules of conduct and we expect our modders to help us keep the comment sections free of any racial slurs or other things that do not comply with these same codes.
To see details regarding our rules of conduct, please go to:
