It seems somehow logical to me that if theymos doesn't allow someone to advertise via banners (like in this case 1xbit), that their signature campaign gets banned too.
Theymos rejects much more than just known scams:
No ICOs
[1], loggable mixers
[2], banks, funds, or anything that a person can be said to "invest" in
I think its enough clear indication from Theymos and he is not rejecting proven scam projects only but also filtering deeply.
