I've had the same thing in PMs. It seems like a lot of words can trigger the spam filter. E.g. names of religions, of companies, anything that could be related to solicitation. Even the word "banned" for some reason. For example it could help to change the word "Amazon" to "Am*zon" (for example).
Same.
