There is a member here that has been doing that. My take was he bought tons at 1sat, "revived" the coin that the dev skipped on, and profited. I will try to find it again.
edit - I must have dreamed this. I can't find now. I remember the member had all of the coins they revived in their signature.
I've seen that as well. I think maybe it was not in the alt coin section. I can't find it either, though.
