I have been a member of several gen forums for a long time. Mostly forums that are either non brand specific or more obscure brands. I know that there are others from here who visit those forums as well as here.
I tend to agree with automatico, however my caveat is the real snobs, idiots and disillusioned belong to the higher end watch forums. These are the ones who tend to look down their noses at everyone who doesn't have a genuine Rolex, Panerai, AP etc., etc.. It is incredible the lack of real knowledge the members of these forums possess. Their knowledge of even their own model, the brand history, notable achievements are a "dark forest" to them. And to make it even worse, they aren't interested. All they want is a venue to show off their watches and brag about what a success they are.
Having said that, it does not one scintilla of good to go on those forums and provoke them. Nothing is gained and all it does is draw unwanted attention to the rep forums. Another point, I don't think it a good idea to operate with the same user name across a lot of forums, especially if these forums are at cross purposes to each other. Certainly there are a fair number of genuine forum members lurking on the rep forums. Some are here to spy, others are just curious about reps, some are interested in seeing how really good the reps are. I have no problem with any of them visiting as long as they are not here to pick a fight. I'm sure that reading posts, they pick up on forum names, especially ones that are pretty odd and not seen often. When they see the same name pop up on the genuine forum, it rings a bell.
My advice like lots of others before me is simply do not mention anything related to, pertaining to or linking you to reps on any genuine forum. Nothing good comes from it. I have a great example of something that happened several years ago on the Doxa forum on WUS. Dr. Peter Millar is the definitive expert on vintage Doxa watches. He wrote a wonderful book on the History of the Doxa Dive watches from the 1960's (Sub 300) to the present (About 8-10 years ago). Probably no one individual was held in greater esteem by the members of the forum. In a post he mentioned that he had purchased a replica Rolex Submariner and commented on the quality and closeness to the genuine. From the comments, you would have thought that he had confessed to molesting every girl in his home town Girl Scout troop!! Fortunately, most of the negative posters were folks who were occasional posters and infrequent visitors. Most of the regulars stood by his right to post what he felt was correct. Their support was at best lukewarm though. No one really wanted to go out on a limb and join his club!! He was very unrepentant, and challenged most who posted negatively to justify their position, which because of their ignorance they couldn't do. He survived unscathed to fight another day, but had this been just any regular member, they would have been tarred and feathered and run out of town on a rail!! So when you are in the den of the bear, don't poke the bear!!
