Downrampers operate using the same principles as scammers and conmen/women. They say whatever it takes to get posters to do their bidding in order to make money. They con you to sell to and either buy the shares at a lower price or make money via shorting.
They play mind games to alter your beliefs.
They make money out of scamming holders into selling.
They use all sorts of tactics. Some are bullies others try to act sincere as rescuers. To many tactics to list.
They usually serial/saturate post so they are easy to identify.
I have them on ignore.
