Yep. It's the client's problem. I understand it. But regardless of what I do, if the relay list is misconfigured, the user is wasting resources of themselves and every single follow that uses their relays. There is no way around it.

Wouldn’t it be better to yell at client devs to fix their apps instead of shouting into the void with gobbledygook that 99% of users don’t care about even if they do understand it?
You have been yelling at devs for a while... Did it work? No client today blocks users from putting these relays in their lists. Absolutely no one. And this issue is not new. Every dev knows about it.
There will always be clients that are too busy to fix it. And in the end, if the user wants to put trash in their lists, there is very little clients can do to block it.
I would imagine that people who use those relays (of which I am one) are like me, and they added them a long time ago when the very devs who you imply should know better pushed them as a good idea to solve problems with Nostr’s decentralization. It’s why I’ve left them there, and unless a client I’m using gives me issues I have no reason to change them. If it hurts you, unfollow me. I genuinely don’t care that it bothers you which relays are in mine or anyone else’s lists.
Yeah, things have changed since those days. If you don't update your lists at some point nothing is going to work and no one will see your posts. This has happened many times with other users.
Each relay adds ~5MB on the data plan of each of your followers. You can "not care" as much as you want and people can decide to just unfollow you.
But it seems idiotic to me to keep forcing wrong relays into your followers just because you are too lazy to fix your shit up.
If you can't fix your own shit, why would any dev fix their shit for you?
