Why is one of my posts marked as SPAM when it most definitely isn't?

[MarvEllis]

Last Sunday I posted a new thread entitled
"Three staff tell me that I MUST use a gmail address (and no other) to log in using new system"

(https://community.three.co.uk/t5/Account-and-services/Three-staff-tell-me-that-I-MUST-use-a-gmail-ad...)

I notice that this post has been marked:
"Marked as spam. If you believe this is an error, submit an abuse report."

It is most certainly not spam and I strongly object to it being marked as such. I followed the suggested "abuse report" link indicating I object to the SPAM marking. I have received no response to this and I had expected my post to have the SPAM marking removed. Could someone please explain why this SPAM marking has been set when I can see no reason for it at all?

What is annoying is that it only takes one word for the system to decide that you have broken the rules. It can be fun to keep modifying the post until the offending word is found.

PS: read your other post and I find the Gmail domain dodgy and use mine only when forced to.
