I don't know about the others, but I found out about 1xbit thanks to a signature campaign. This is why promotional campaigns are done, to attract new users, right?
This is why you seem weird in my opinion. You created your Bitcointalk account way back at the end of 2013 and you claim that you never heard of 1xbit until they hosted their signature campaign which is tough to believe.
Shilling is cheating.
I just support the project that I advertise in my signature, is that weird for you?
What I actually find weird here is the fact that you admit that shilling is cheating and you still shill for a scam site like 1xbit. If you had a conscience, you would never support this site.
