regardless of who it is ......bad language and crude/obscene onslaughts on fellow members cannot be tolerated .......no matter how passionate the other member feels about the situation ...o indeed no matter how respected the member is...Depends on the level of bad behaviour, and depends on what your priorities are.
What Wasp posted for example (according to reports) was illegal, and that's obviously bannable and should be deleted, regardless of anything good he might provide regarding trading. Criticising the way someone does their job, is not remotely the same.
When you say 'bad behaviour' what exactly is meant? How many posters here haven't at one time or another committed some bad behaviour?
the Forum (and whatever member involved in the exchange) wont be taken seriously in the long term..........let them go to other sites
