Is that the first multisig address to solve a solo block here? Congrats!
if it was west/nicehash account:
from their page:
"Do NOT mine into this address directly! Mining payments to this address will be ignored and considered as donations! Also, do NOT use this wallet Bitcoin address for pool username when configuring your miner for mining on our stratum servers. Use your own personal or cloud Bitcoin wallets for mining. This is a deposit address only for buying hashing power. Thank you for understanding."
We have this in place so that our own miners don't mine into these deposit addresses. When they were doing this, we got extreme quantity of dust, which was hitting performance all over the place, so we decided to prevent this.
This being said; we do not prevent mining from other places to this account which means you can mine from here using our deposit address.
