Does Mods selective, when banning members?

Well I was once get red Infractions from mods when I post here about how mods treat mods not equally.

I hope this one will not cause me another red flag. But I hope we have freedom here to tell what we feel.

I hope I am wrong with what I am thinking that mods are selective when applying the rules of this site.

Why I said so? I made one mistake 2 or 3 weeks ago by posting something like "PM me for more information" I don't remember the exact word and instantly mods banned my account for 1 week.

I am not complaining that the mods banned my account, I made violation of the forum rule so I deserve to be punished.

What I am questioning is that there are so many members also doing the same violation and I guess do it not once but many times but I never seen them banned.

If mods answer they can't monitor every thread and post I understand that too, but I am helping them to find those post by reporting all those post and thread that violating forum rules but I din't see any of those post I reported get banned.

For example this member, he is very new and I reported him twice I guess but no action taken.

Once again sorry for the mods I know you have hard job here. But hope if you apply the law to other member you apply them also to other even you personally knew those members or you're living in the same place or country.

Just my 2 cents
