I've only ever had one problem with a seller who took PayPal and it was fixed a couple of hours after I complained to PayPal. I never knew if it was coincidence or PayPal's doing. I don't know that making information easier to read is such a big deal but every little bit helps.
It doesn't seem like such a big deal to me, either, but apparently it was a big deal for rather a lot of people. Funny, huh? I guess what's clear to some people is hazy to others. Anyway, I agree that anything to clarify their policies is a good thing.
Yes, this is pretty much a given, unfortunately. I've been seeing that more and more lately all over the net. As soon as something is working well and people like it, soon enough troublemakers will come around to ruin it for everyone.
