gg5 (嬲り物): an object [a butt] of ridicule; a laughingstock; a mockery; a figure of fun.

嬲り者 and 嬲り物 are the same word. There's no person/thing distinction in this case.
As the n-grams counts are relatively low, I don't think the kanji forms need to be in strict frequency order.

Kokugos merge with the 物 version, though I don't think we usually do that.
