I keep getting a message that the DM appears to be spam.

Please help.

I frequently get a similar message when I try to send private messages (PMs). The error message says that my message is spam-like or contains inappropriate elements (screen capture below). I’ve found that if I try again at a different time, sometimes the message will post okay, but it can take several days of trying before it works.

Seems to be a bug in the Xenforo software.
