That is a risk to our pool, we will try to contact this miner and confirm he is not faking this hashrate with some special method which is already known to us, if no response from him received , we will have to ban this miner.
We have been keeping our eyes on you, don't try to fu*k us and our miners!
Hey potential "thief", if you read this, we have banned you.
We won't let you in until you contact us and prove your hash power.
We have closed our registration at the present , sorry to new miners
Quite easy to check: Nr of blocks found vs hashrate vs global hashrate. No 'marginal' differences, then no problem. if you do 1/3 of the pool it is noticable if you cheat ...
