Gets quite awkward for me too, for example last night 2 of my customers were arguing on there (posts have since been deleted), could see the merit in both their arguments, however I'm just going to open myself a massive can of sh!t if I post anything on either side of the fence!
Also made me laugh that I was apparently posting negative comments about those dodgy lift kits out of "commercial interest", not based on facts... But like I said to them, if someone wants to pay £20 for a lift kit, they're not going to pay up to £150 for a kit, that's not my market! I don't deal in bodge jobs! Most of them had a heart attack when I told them what a proper lift kit costs!
