So… what is your question exactly?
Edit: got it ;)
If there is no presence of ATC you can’t really do much about it. The only thing you might can do: contact the player on the forum if possible. Don’t blame him/her, just explain :). Giving them a chance to learn and getting better.
The easiest way for me is to stick with the ingame METAR information. The second digit combination tells the best option to go with.
Also a good read if you do not know it yet:
If there is no ATC present, there’s not much you can do. What you can do is PM them if possible and try to show them the proper way. If IFATC is present, then it should be resolved as the controller sees fit according to the User Guide. But you can continue doing your part by doing things the right way and setting an example for the pilots :)
Sometimes the ground wind doesn’t even matter! It is possible that right after take-off at around 500ft+ or maybe 1500ft+, the wind may be a very gusty tailwind which pilots would rather not face and take off in the supposed “tailwind” in order to reduce chances of potentially stalling or reduced airspeeds.
If you fly often it IS common to see on FR24 to see an airport use a set of runways while even an IFATC controlled airport is using different runways compared to irl.
