re: does this mean that all business promoters will be banned
I would imagine this will be the case if they are in direct competition with the owners of the site and ignore any warnings which are given. Like yourself I found a lot of Amanda's comments really useful and I don't claim to know the full story and nor do I want to but I do think that to posters on the site it seems the ban has as much to do with personal disputes as anything else. It is a very sad situation.

Not 100% but I know that PP in particular is very fair and does give a warning if he has to delete a post and from what I gather he is a very good friend too ..... I have also seen posts which Arron has removed where he has stated why. From what I gather this decision has come from the owners of the site not the moderators ( Arron, PP and Dan) and the decision was beyond their control.
re: does this mean that all business promoters will be banned
As much as Amanda's advice is usefull it did tend to be used as a vehicle for self promotion to an extent. I may be wrong but it came across that way sometimes.
