Dear John_1:

I agree: an anonymous apology is not an apology. And yes, I think this “apology” is not sincere because it is not complete (the name is missing as well as WHAT it is he or she is apologizing for!)-

It is not necessarily someone having fun doing it. It could be your ex kind-of wanting to apologize at one moment, impulsively producing a very lacking apology, a kind of an apology-like, on a moment of impulse and then going about her business. If not malicious then it was impulsive, lacking thought, lacking maturity.
