I couldn't log into my account today, and to my horror, realised that I had been frozen!

I just can't figure what I've done wrong as I only go on Neo to buy stocks, collect bank interests, etc. I know most of the rules breaking come from the Neoboard so I generally avoid it. But a few weeks ago I got a faerie quest and asked someone for help there. I thanked them by calling them "sweetie" and is the only time I've been to the Neoboard.

Could that be the reason of being frozen? This only came to my mind after realising words like "uncle" are filtered.
