Well, to be honest, without offending, I don't see anything wrong, the user just wanted to share information that he found useful, and I see it from a good point of view, I don't think he wants to cheat or anything like that, I think that if a person follow the advice of another is under their own supervision, it is up to us or those who want to enter certain contests that are outside the forum to do the required and pertinent research.
I don't see it any other way, some speculations can be generated but there is no need to echo this much, just someone who wanted to share this and that's it.
I don't see anything wrong either.
Not every time such an event is announced does it always have to be an in-house representative. It can be a player who likes the event and wants to share it so that more people know about it.
To me anyway that kind of freerolls do not attract me much, it's a bit like playing the lottery for free but you have to be actively playing for a long time to try to win.
