If by the private key you mean a link to the profile, yes I can provide this but only to the highly interested parties via PM!
Yes it's bitx campaign and they offer 150 posts per week at the price of 0.0008, so that makes 0.12 weekly!
No... Private key associated with the account. As in the private key of the address associated with the account.
Also I forgot to mention that you probably shouldn't give out the profile any time under any circumstances. Because then people can mark the account easily as sold and such.
