ok, here goes:

We are to remove all workers except one (the first worker that you've created) at minerals.pro pools in ~1 hour (00:00 GMT)

You will not be able to create more then 1 worker per account after the removal

Please make sure to leave only first worker mining Minerals

PS: if you have several small mining rigs you may use 1 worker for all of them, all valid shares that they produce will be accepted just as well as if you were using multiple workers for each rig.
