I was a pretty huge JJP fanboy and bought their first three games. Anytime I needed customer support I received it but it was certainly a janky process at times. You never knew if using the website, an e-mail, or a phone call would get you the help you needed. Usually a phone call worked.
I think, as with most hobby communities, there's a super vocal minority that has had a bad experience and wants to make sure the whole world knows about it. This can make it seem like there are no happy customers but the happy ones just don't share their feelings that often.
That's not to say those with faulty products shouldn't be compensated but there's definitely an echo-chamber on PinSide.
I'm no longer a fanboy and sold everything except WOZ however I would still buy another one of their games if I liked the theme/layout regardless of PinSide's opinion of things.
