If this only message is enough to tag accounts then Wipro could post similar announcements in the topics of managers he doesn't like and these members will be tagged also.
People who don't work with someone would prompty complain that this happened[1] and/or report it to moderators and would not get tagged. You're wasting your time defending fraudulent managers, which are one of the fundamental pieces supporting the problem that we have in the ecosystem.
[1] e.g. I would do all of the following as soon as I'd have seen it in my thread: Tag the user, report his post, make a thread about it. I'm sure that anyone reasonable would do the same as soon as they notice that they're being set up.
