I don't think this threads of selling of stake account accounts and this Ranking Up Calculator threads are created by random users from stake or forum users but I am suspecting that they are from stake officials. And if anyone wants to rank up to vip level in stake, there should be a guideline in the website to do that and not a separate thread a d links which might link someone to another different websites and got scam.
And my fear is upon all these extra threads, stake has not said anything about them.
I did not see any were that the ops mentioned account sales and he did not offer a leveled up stake account for sell and a price tag, but what I have seen is that, he made this thread in Bitcoin discussion board instead of making it in either gambling discussion or games and round amor any appropriate boards asides from Bitcoin discussion board.
If this thread and the link is all about calculating your stake vip account activities, it then means the link can be useful to stake user's who may be missing out in calculating their progress as regards to VIP ranking and what requirements, I think what amount to VIP mostly is based on the number of wagering that the member have done
