I’ve let our admins know about your ticket. Please see the many, many topics where it’s explained that this is due to an automated filter that’s set very aggressive with the intent to catch spambots.
I don’t know how to make a different post, because there’s no visible button “create” on android, but this is also my issue I’m dealing with. It’s all described in my ticket (365363) and I will be glad to be able to comment for once on this site
