Who is truly being helped by someone posting some platitudes on a suicide forum? No one's life is really going to be changed suddenly after hearing "it might get better, don't give up!!" or whatever. I assume most people here are suffering from problems that can't be solved by someone deciding to post some positivity thread, even if they mean well.
This isn't "help". It's emotional comfort at best, if actually genuine, sincere, and offered without condescension or expectation, and I and I think most people don't have a problem with things like that. But at worst, it's useless and aggravating.
This kind of "help" is offered to anyone expressing any kind of suicidal intent aggressively and constantly, without any concern for whether it is wanted or whether a particular individual will actually be benefited by it in reality, beyond fleeting feelings of well wishes.
As @hotelbeneathground has said, concrete help is what actually matters.
