You're absolutely right, getting accurate data is one of the biggest challenges we're facing at the moment. I'd like to believe we're making great progress with it though. :)
Initially, we started off with static data together with a management panel for hosts to add/edit/delete their offers. As you might have guessed, most providers didn't feel like doing this, and those that did made mistakes entering the data or didn't keep it up to date.
This is why we've put most of our effort into automating the data feeds and getting up to date information. Right now, 60.3% of our offers are automatically retrieved from the provider and kept up to date every 24 hours.
Whenever a provider adds, edits or deletes an offer from their website, it's automatically synced to our website accordingly. We also try to do this for stock, but some providers do not expose this information before ordering.
While I'll freely admit we still have mistakes on our website, I hope that it's still useful in finding the right server for your needs, and appreciate your patience while we keep working on improving it every day. :)
P.S: We have deployed some small scale machine learning and are experimenting with it as we go, but since our knowledge in this field is lacking, progress will be slow.
