It seems you've run afoul of an issue known as the "Scunthorpe Problem" or the "Clbuttic Mistake", where a poorly-programmed profanity filter picks up on what it thinks is offensive language, when it's really just a string of characters in a larger word that isn't actually offensive.
In the case of your chosen username - Espicheza - the word filter is probably picking up on a derogatory four-letter term for people of Hispanic descent that is contained within the aforementioned username.
(On a side note, the aforementioned issue is often the cause of unintentional hilarity; for example, if a word filter is programmed to not just detect potentially offensive words, but replace them with less-offensive words, you often wind up with situations where the word "a.ss" is replaced with "b.utt" when it shouldn't be... such as in the case of the word "classic", which becomes "clbuttic" when affected by such a filter, hence the nickname "Clbuttic Mistake" for the problem in question.)
