You should probably list all the snapshots that you're looking for in the OP such as clams/BCC/BTG, etc.
This way people won't have to bombard you with thousands of addresses that contain nothing of importance and nobody will accuse you of ripping people off. AFAIK lots of people are saying they're buying old BTC addresses and say that it doesn't need to contain any funds and "any address is fine" but in the end they only want the ones that will make them a profit.
Just a suggestion. You don't have to follow up with it if you don't want to.
Yes I understand, but listing out all the forks simply means anyone can claim the coins. Most people including myself buying addresses are hoping to get forked coins that other do not realize they even have.
