Since you posted to "none", I figured you wanted all input.
IMO it's not a violation of the TOU to call an officer of a public corporation a swindler unless the post was posted directly to him.
As far as a poster calling another poster a pumper or a basher, that would be a direct personal attack.
If the poster used the terms in a general statement about the company/stock though, I don't think it is a personal attack.
For instance,
The pumpers/bashers are really going at it on this company/stock.
should not be considered a personal attack.
All IMO,
Phil
