Although I'm nowhere near the level of members like yourself Robbie, I can sympathize on what you're feeling. I've noticed that lately there many "hit-n-run" type of members joining our forums. This is probably attributable to the fact that there has been a flood of so-called Super-reps in the rep market in the past few years. I guess you can sort of view it in two ways. On the one side, it's good that the rep world in general has been growing more and more popular for the masses and on the other is that it will inevitably draw those who will pop in for a rep here and there and never really take this on as a hobby like many of us have.
So like everything else in life you have to take a bit of bad with the good. Personally, I always attempt to maintain some form of decorum with every member I interact with. You never know who might become a life long friend. Plus you wouldn't want others to judge you based on what little info we're privy to from the forum. As a buddy of mine used to say, "you never know if that noob you're talking to might be a Supreme Court judge". LOL
