If this is the case, why is it allowed to post details of dealers and repairers you'd recommend. Is that not 'advertizing'
Of course anyone can say or recommend who they have had work on their car etc. There are many recommendation threads including "Stickies" in GAD
& many of the Regional Lounges for both Dealers & Independents, which are very useful resources
No of course not because those are "recommendations" not " advertisements"
As I've said elsewhere before there isn't a "no advertising" rule, however you do need to be an Authorised Trader to advertise on AO.
More info here Alfa Romeo Forum - FAQ: Trader Advice
If you want to advertise on AO you need to pay to do so, if you don't want to pay to do so then don't advertise, simple really.
It costs money to run a forum even more so for one as big as AO & the revenue from Traders/Paying Members helps to keep AO running
& also keeps AO mostly an advert/banner free forum
PS I don't think Ti need to worry about posting adverts as they are always the 1st recommendation for anyone in the area.
