User reports being filtered as spam and I believe it may be Akismet

I received a message from one of our new users that is not able to make comments in EasySocial. I am thinking this is caused by Akismet because I had an issue like this before. But, I am not sure. Have you heard of this happening to anybody recently?

Here is the message I received by email from jan_ryan@fastmail.fm:

Hello Sean,

I have had problems when I try to post comments/replies on my timeline and photos, I have tried multiple times. I also have logged off, relogged in, and retried again. I still am unsuccessful.

The error message is:

The system has flagged your message as a spam. Please try again.
