I know its annoying (especially when i see 1 person trying to mine) but there is not much i can do.
Will try to mine to the windows wallet . If doesn't happens there too will shutdown that port so the person to stop losing hash power and auto-switch to his second pool .

Other than this i dont see any other option what to do .


Regards.


P.S. Will write in 10-15min whats the result
