It's not unknown for someone to join the forum just to give their business a plug. There was only one comment intimating the two pro the sellers plugs were suspicious and someone quickly posted that one at least was genuine.
It seems a little bit of an over reaction to take offence so quickly and easily. This forum is a great place to promote your business when all that is required is a bit of give as well as take and contributions that occasionally extend beyond the line of business your are in.
I would hope that Lawrie who may not be aware that there are people who in the past have simply taken advantage (or the pee) will reconsider and not be put off posting again in the future
