Unknown 'Frink" message when cleaning

I too have be Frinked. I had been getting it occasionally since Halloween, but it is almost a daily occurrence now. I am also firmly in the camp that this is a server problem, and is a default name when it loses track of the actual tapper. My reasoning: I have several feeder towns. I also have a daughter. My feeder towns are only friends with myself and my daughter. My daughter is only friends with my feeder towns. It is in the feeder towns where I see Frink the most often. There will only be 3 taps, all from my daughter. (I don't bother to tap my feeder towns from my main.) Two will have her name, and the third will say Frink.
