Why could I not create a topic before posting?

It’s civilised discourse to let accounts be ‘disappeared’, practically, without any rationales whatsoever? Discord does the same thing (maybe it’s all those that begin with ‘dis’…) and I think it’s the worst online practice.

By the way, it’s the opposite of ideal… I just gave up and posted some irrelevant topic on someone else’s years old thread (due to being unable to start threads), which is clearly what is encouraged by default in this software… (oh, and a few minutes after the level magically bumps up, at which point, I suppose, it’s sensible to delete the post on the irrelevant thread and create my own thread… if you seriously think this is at all close to “ideal”, I swear…)
