The concern is bashing. I’m sure if one just stated their concern it wouldn’t be an issue on FB. However, if one repeats it over and over, they do get annoyed. I don’t blame them (Pepeoil and jmjjw are garbage). The only thing I can suggest is to sell and move on. It is understandable if one feels a stock is not working for them, but it is not ok to sabotage another’s investment because you aren’t happy.
