Okay, I don't offense about your site, I talked about a similar logo only. I agree with you, similarity is not the same.

For each member we offer affilate program. It seems that this domain name owns someone with our affilate link.
As well our marketers buy advertising from many sources and 3rd party exchanges, if someone bought this domain it is possible that there is a link to his/her account connected to our affilate program. Certainly no one should do that, we forbid any fake or confusing links.

I will definitely pass it on to our team to check that redirect.
