I also thought it was the gold banner.
I think I will email blizzard about it being present in modforge and dota and see if they remove them too or if they tell me which was exactly the reason.
Although I don't really think any of the sites actually needs to be listed there.
Edit: I won't email now, cause I found that that modforge's ads to gold things on wow were unintentional, they are google ads' fault (I am sure that any site with the word warcraft will end with those adds in google adds)
It seems that the gold banner is the reason, in my opinion I would rather let the site get the so needed money that banner gives to it so it can mantain the expensive hosting rather than getting rid from it just to be listed in the same place that lists modforge, thehelper and dota (no offense, but not worht it...)
Edit: Don't forget the Link to BNET's MAP DEVELOPMENT FORUM! The WORST wc3 modding site ever, Full of morons and perfect for :
1) "map protection" flamewars.
2) "Map unprotection" links
3) "map protection" flamewars.
4) morons
There is nothing more in that forum it is so horrible.
I think thehubb doesn't deserve that humiliation of being listed there either
