Peter, I don't think the overwhelming majority of posters block those with differing or negative opinions on GBG or other stocks. What people who hold don't like is low content posts that just "bag and brag". Down rampers often just want to 'brag' about how they are correct and 'bag' holders as losers who should have taken more notice of them.

GBG is a sad case. A number of factors have contributed to this and holders take the consequences. That is the market. Investing is a very emotional pastime. If you have a negative view on GBG express it and the facts but don't infer how you made a lot of money because you did the 'correct and intelligent' thing.

Everyone wants to be correct and the share market is a jungle but personally I find some 'down rampers' (as you term them) very pointed posts regarding the decline in someone else's asset very depressing. There are many down rampers who don't hold and in their first post just points out how right they were and how much of a loser the holder is.
