I joined Genes Reunited last year, and while I didn't get a lot of info, I was able to eliminate a lot of leads.
I was able to read a number of family trees, made available to me by the authors.
But I let the membership lapse, and found that I could no longer access any of the information others had allowed me to see........though those (if still paying) customers were able still to access my files.
So, in a fit of pique.......I deleted them!
As far as I'm concerned I'd already paid for what I had available.
