I don't consider sharing your seed phrase with others as a form of scam; I see it as an indirect giving out of ownership to the next person and a stupid behaviour by the person who shared the seed phrase since it's always boldly written even before you finish setting up any wallet that you should never share your seeds, but if someone out of willingness someone still considers doing that, then it's no longer a scam for the person who stupidly gave out ownership of their money.
