Well this is for feedback so here we go
Being blocked for quoting messaging apps in 1to1 messages seems a bit mad .
Are they illegal or something?
You come on for connect to people ,there's only so many ways to do it and you're blocked.
It's against the rues to mention rival sites/apps, I don't why that is a problem, would you be happy if your business was being used as a platform to advertise rival businesses?
The moderators clarified this last week didn't they? You are free to mention them in private 1 to 1 messages, but not in the forum or as a status. So far as I recall anyways
