There's much discussion about what constitutes advertising in the comments, with some dismissing this question as either solved or not crucial. Note however that seriously banning advertising requires a clear definition of it.

My 2 cents: Ban payed advertising online, including banner ads, search ads, and pre-roll / inter-roll ads (e.g. youtube and instagram).

This is a clearly defined market and probably causes a plurality of the negative impact of adverts (especially when connected with the incentive to algorithmically addict users to show them more ads).
