I also dont understand why pupils get negative trust if they just writed a topic becausr the maybe dont know rules.They dont read rules today world is fast.I would give them only warning in pm and if they repeat they got negative trust.I dont like this bann and red trust system I was banned in past because of referral spamming so i created new account but i was banned because copy paste posts i didnt know that i cant do that and no warning and i got bann.
Believe me, it's better to see red trust when you're newbie and you can just make another account.
People have to learn somehow to read the rules, behave nicely and see this as a community of people with a common goal, not a bunch of spoiled stupid rich kids easy to be scammed.
Then this forum would have a better name, Bitcoin too, there would be maybe 1/10 accounts, but much better ones.
And the trust system is the only system we have. It's not perfect, but not bad. By your idea somebody will have to keep sending warnings and keep track of them. Time is money.
With current system, anybody can give feedback. Sometimes it's not deserved and it hurts a lot, especially if the account is high rank. But most of the times it is well-deserved. OP clearly deserved it.
