You make a good point. I also used Telegram some years ago and never gotten invites to questionable channels, although I think you can search for channels in the app. But another way to learn about them is through influencers advertising them on social media like Twitter, facebook, insta etc. which brings us full circle xD

on twitter it's in your face

I wrote a lengthy paragraph and realized that I don't know how bad it is, and how to act accordingly. I agree with another person saying, that they are against bans on media. Maybe the EU could offer a compromise: Abide by some fancy schmancy laws that address content moderation or get lost. But then again, I do not trust politicians in the EU parliament to a) understand the technology and it's limitations b) be interested in this, since there are many conservatives who could actually benefit from twitter being in the state it's in.
