all sounds like abject bedwetting to me.
If the culture of lfgss is too rough for your delicate sensibilities you obviously shouldn't be posting there. I mean, you already admitted you don't life in London or ride fixed (which isn't an obstacle, but still a good indicator of target audience...) so doesn't sound like it will be debilitating for your social life (if you have one).
You seem particularly put out about the 'fairness' of being banned for breaking the rules 'accidentally'. Hmm. How many posts did you have? Did you try and justify yourself? One reason the classifieds there works better than say, ShiteRadar, is because chancers coming to punt something at double its worth get told to sling their hook in unambiguous terms. It's ******* annoying when a total flange turns up, posts 8 times in really banal ways to start a classifieds thread, then thinks that he can flog his rad Carlton gaspipe frame for £300 to some London hipster. If you got caught in the crossfire that's unfortunate but i don't think you need to take it so personally.
Criticising the business plan/valuation on here, and focusing on Velocio's supposed 'customer service' (you're not a customer, nor an investor, so it's a strange term to use) just sounds a bit bitter. Search for just about anything to do with road/fixed riding in the UK and lfgss will probably be in the top third of search results on the first page. Speaks for itself. The quality of the site is also down to the user-led moderation to keep the two bob mug cunts and chancers away. You can call this pretentious or whatever you want, but there's less random chauvanism, racism or bullshit led 'banter' on there than any other white-collar wanker focused cycling site out there and people like that.
Maybe you should just put the petted lip away and accept that you did something you shouldn't and that your participation/contribution to the site to date wasn't enough to get a reprieve, or that the admins have more to do than dry your eyes for you.
Have a wonderful afternoon.
