ID ver is not only against TOS. But also illegal in many countries.(Like owner of discord can literally be declared a wanted person with sentence up to 20 years for literally having pictures of 30 other people ID`s)
If Rahi would attempt it. They could lose their PayPal, Patreon\SubscribeStar and Google account, not just discord group if anyone decided to seriously pursue this.(and we know stalkers do exist)
Please dont break TOS or laws of your country
P.S. Only thing you can do on discord. If someone say they are not 18 is to ban them on a spot. Thats pretty much it.(since age verification is just yes no thing)
Other tools are either against TOS or against law of certain(many) countries
