I get more vexed with shy inadequate losers who masquerade as schmoes on forums. They really pee me off but I reckon I have a good radar for spotting faux-schmoes (faux-schmoe is a good turn of phrase isn't it!? Remember where you saw it first😃)!
Why does it anger you? It should be a given that any person posing on the Internet as a muscle woman on a muscle woman fetish website is lying. Unless there's a verification system in place to prove it's a woman, it's safe to assume it's a man. No need to get mad about it. Just ignore them or laugh at the schmoes falling for it.
Some guys might need help with this. For others, this thread might provide some humor.
For example, whenever you see the word "goddess" in their name/username/handle, there's a 99.999% chance it's a schmoe in a thinly veiled disguise.
Feel free to post other obvious examples here.
