I got PRSOM for anonymous post Watch
Has anyone else ever got this before?
The user that wants to rep you can't because he or she has repped you before and cannot continuously rep you and only you.
It means that the anon post was made by someone that you have already recently repped
The rep goes to the account Anonymous. If you get PRSOM for an anon post, it just means you've rep'd another anon post recently.
