there are various degress of ramping as well ranging from people who hardly post with their one liners - through to others who just go along in heavy volume stocks making it look as thoguht they influence prices ie mosntercrash.
Then there are ex employees with a grudge and confidential information or disinformation ( we have seen the odd one here the impact is normally non existant on trading volumes) they come up post heavily and then disappear a couple of days later when challanged or have HC remove their posts.
Then there are those that talk to themselves with different nicks ie fredifish and pixiemops.
