After the first nagging about mention a team member I haven’t mention anyone. It was the safest road, and I will keep that strategy.
But… I don’t even need mentions. I write in topics and sometimes I get answers, sometimes I don’t. Mention someone doesn’t change that. I might quote someone instead, because it does same thing. And I don’t even know who I would mention 
My opinion still stays — a house full of coders could tie ability to mentions of team member to higher TL, because they know how not use is. And give a small informative message to (new) members who are trying to do such trick.
Because even I kind of understand these topics, it sounds a bit rude when (new) users are using tools that they have and they are used to use. No-mention is not common policy out there.
