It's a random word generator. It takes random letters and assembles them to create names. The connotation of the word was not offensive at all; it was a script, not a person directing it at anyone. Take this with a grain of salt and understand that that kind of stuff happens.
Tamatalk is not unsafe merely because the name generator generated an inappropriate word. No user directed the word in question at anyone, it was merely a few lines of code generating letters.
The likelihood of it happening again is very slim. I wouldn't worry too much.
