I’d also argue that regardless of the server size, it takes literal seconds to explain why your account is getting banned, it’s absolutely within the realm of reason that if your system allowed automated signups that you as an admin have an obligation to not be a shitcunt and at least give a reason as to why you’re banning accounts.
I’m pretty fond of these little Velcro straps I got from Amazon that are like 10cm x 30cm, you use them to push all your computer cables into them so you can neaten them up. I’ve got several of them strapped back to back and it’s a pretty decent solution (and being Velcro you can just pull it apart later on)
