A tad late to the party here, but just to add to the information given thus far (should a new player come across the discussion or something), while human effigies are not infinitely farmable without the use of a bonfire ascetic, the OP voices concerns regarding the reversal of hollowing. This use of the human effigy eventually becomes irrelevant as humanity can be restored via the Srine of Amana (provided you have no effigy's on hand. Though that said if you do have effigy's you can simply use them as always. When the supply is used up, the shrine replaces the functionality. This also means you don't need to feel pressured to ramp up NG+ levels in order to farm to regain humanity)

Also as was previously mentioned, you could get summoned, but that is dependant on something the player themself aren't in direct control of.
