I haven't used BL and PR for such a long time. Recently, I've been reading both quite a bit, keeping an eye out for what's floating around. The only genuine purpose PR now serves is highlighting the fakes and duds. It's become completely unreliable, which is a shame.
I think it's worth having a discussion on how you users are able to submit new reports. We have to ask how beneficial a 'positive' report is without an image, video or test report. While anecdotal reports can be interesting, we're all only really interested in completely positive reports or reports of fakes.
Of course, any barriers you put in place will be worked around by those who want to abuse it. I suspect barriers like those mentioned, will also lower the number of reports we see on the site, but might increase the quality and authenticity of posts... maybe.
I prefer this thread and the opinion of EADD's regulars. Most reliable source of information.
