Its not possible to simply past a wallet address and mine ZIL. You are forced to hand over the secret codes of your wallet. So take care of your codes. Never hand over your private key.
Want to take that risk? It's fine to me but I quit mining now. Never received ZIL in my wallet.
Thats your fault dude, maybe you ask what the problem is and we can help you out but don´t spread bad vibes if you make a failure.
This software work fine and swaggadon is owner of shardpool.
And by the way there are miners out for mining zil+eth or zil+erg without this switcher.
