They are good, but people like to give the mods the best experience (which is surely biased), and the service provided at the time of the mod review will be different than the service provided to buyers several months later.
There are content services from 2012 that haven't been reviewed by a mod in 4 years, for example. The writers and quality will have surely pivoted by now, so that's where I'll come in a re-test it.
Also, I'll account for things such a pricing for what you get. If you're paying $15 for an article, I'll only give it a stamp if it's worth at least $15.
