Sub-Forum Inconsistency

Moin! There is something about the subforums that irritates me here. No, not the subforums themselves. They are a good idea. But why can you still write in the “Grundforen” if subforums exist? For example, there is an “Audi A3 & S3 Forum”. There are subforums for the old “A3 8L”, and one for the newer “A3 8P & 8PA”. So far it makes sense. Only there are still many users who can’t decide whether to drive an old or new A3. And garbage The basic forum (“Audi A3 & S3 Forum” with their questions too. In the golf forum just like that. For each golf there is a subforum (at Golf VI even with sub-sub-forum). Nevertheless, almost every day someone writes directly under “Golf”. As if it were so difficult to post directly to the right model. And in ten other MT forums it is certainly just like that.. My question (or better please) to the mods: there is a reason why in these forums despite many suitable sub-forums still new Thr And don’t you even want to change that because of clarity?
