You are such a rule expert after you made only 21 posts in forum and you are teaching me how this will affect me?

If I register on any forum, I make sure I read their rules. But I am not a newbie on this forum, I just decided to have better privacy with my online life. Not only just on this forum, also the exchanges that I am using, and the wallet that I am using. Many people among us have made a huge mistake by sacrificing our privacy but I am not doing that anymore.
I didn break any rules and I didnt post multiple posts in a row in the same day, and I had nothing to bump up.
I understood what happened, it is happening to many people on this forum but it is still about posting on a row. Moderators have started doing that to some people some months ago. Just forget about it and move on, it will not affect you.
Friends, is this mass deletion considered spam, or has someone reported your posts? I don't understand this rule. Why are posts being deleted by the moderator?
Is it because the post was deleted by a bot for posting your own quote? So it's not allowed?
Moderators are doing that if they see it. People are not reporting it, that is the reason it takes moderators longer time before they will see it.
The right thing that people should do is that they can post it, leave it for one or two weeks, delete the previous post and merge it with the new one. But that can be done immediately, merge the old post with the new posts in a new post, that is better.
