Sorry, I've never encountered any problems adding friends.

Odd. This is happening to both my housemates, my partner and one of my irl friends. o.O

Is 100 the max?

100 is the max, yes.

I suspect that if the other person's friend list is full, it erroneously gives you the error message when you try and accept them. That's the only thing I can think of.
