Ioverlander database has provision for tent friendly classification as part of the description for every accommodation type entry.
Of course not every entry will have all classifications filled in. Tent friendly and pet friendly and showers and toilets dont interest me in the slightest, but bigrig friendly and internet does. Even then i take the time to fill in every box and take photos as well.

As for fuel stations entered as informal campsites (not usually interested in fuel stations as such except in Bolivia because there are tens of thousands), in many places they are all you have and it is up to you to decide if it is any use to you. Some ARE tent friendly, but many are not, just as are many hotels that allow camping really mean you can park and sleep in your vehicle.

The info provided is what you and other travellers provide, so if it is incomplete, then just fix it.
Btw, using it via an app means you cant use all the features. On the main web site you can select to download lists and poi files of only those places that for instance are tent friendly. Then you can download that tailored poi file, email it to yourself and then add it to mapsme or other offline mapping and navigation app and end up with your own special tentfriendly app. Then your problem will be to hope that whover entered the info was a fellow bike rider or pogostick rider or whatever and understood exactly what tent friendly might mean to you.
