why many posts are deleted when they think to post them carefully and is there something wrong in their post so the moderator deletes them?
a lot of harm to the workers because it reduces the posting requirement because it has been removed if this will impact on users so they leave the forums?

I've had some posts deleted in the past, something in the range of four. If I recall correctly, all except one were for some early days airdrop subscriptions, when one followed the trend of the previous guy without really knowing if it was the correct way to participate or not. Eventually (rather early I’d say), I gave up pursuing (the few) bounties and airdrops I joined, since I kind of felt that I was giving information away for peanuts at the best. I even saw my account appear at least once on one of those “please nuke these 1 trillion accounts”, so that didn’t really boot my wish to keep on at it.
As I said, those were early days, and the amount of deleted posts in my case was minute. There was one other reply that I posted that got deleted, probably because the OP of the thread created a rather dumb seven word post with a prophecy on bitcoin crash being imminent. I came back to give a sample of seven word quotes that were infinitely more meaningful. The thread was probably trashed for being a tarot fortune-teller’s guess, and so end of.
Having a few posts deleted is really a drop in the ocean, and happens rarely to one if being on topic, and not spamming gibberish. The problem is that if you add up all the drops created by all the forum users (some come with cups or buckets full), they add up to a meaningful amount, thus the forum’s effort to deal with this issue (because, it is an issue from the overall point of view).
If the amount of posts being deleted for a given users is significant, then we can infer what kind of contribution that user is adding to this forum.
Also considering this a job (“harm to the workers”) is also not the best mindset.
