While I dont disagree with all your points, your wrong about them going away. Just review their posting history, I can show you boards they post on almost daily for years, even tickers that dont trade at all, look at INOH for 1 example.
Those clowns are like professional politicians, doesnt matter what is posted they will spin it, minimize it or discredit it and if they cant do any of those things, they will delete the post. Sure you can complain to admin but that doesnt help either.
You post on TPAC, so I am sure you know what they do. They tried it here too but the site owner ban them. They do still post here but they are very careful about what they say.
