The straight razor community has the exact same issue with sub standard blades and the accepted response to the issue on forums is also to use the full term as the abbreviation does carry negative connotations in English even when unintended. I support this and suggest that the first line of defense is to send a well meaning PM to the poster explaining the situation because they likely have simply not thought about it and request that the post be altered. In my experience this has only worked out very positively.
