Not Bug Fame glitch?

Has anyone ever had a problem with faming before. I tried to trade fame with someone today, he famed me, and when I tried to fame him it said that I couldn't anymore for today. Before that though, I hadn't famed or defamed in probably two weeks or so. This also isn't the first time it's happened to me.

 

Oh sorry, CowboyTanaka

 

Had you famed that person within the last month? You can only fame a certain player once per month.

 

That is definitely a possibility. Unfortunately, I can't remember for sure if I did or not.
