Sorry to come late to this resurgent discussion.
This is not an easy issue to deal with and the compromise which was reached (and that what happened) inevitable goes further than some would like and not as far as others would wish.
In defence of what has been agreed, some other very popular forums have far more draconian rules, while others are more lax. In general, it is commercial sites that are strictest as such sites do have to protect their revenue streams.
Inevitably there are those who believe that the internet is 'free' and that the only 'censorship' should be self-censorship, but it is a fact that the rules for this site have to be a balance between generating the income to justify its costs while keeping it a useful forum for the members.
Ironically, in many cases it would be easier to lock a thread or delete a post rather than edit out links, a process which draws attention to itself. But we feel it is fairer to at least try to keep the sense of what a post or thread is about.
It's fair to say that it doesn't take much expertise with search engines to find the subject of such posts but it does stop links on our website appearing in searches. As this site ranks highly on Google etc. those links are exactly what the operators of certain sites often pay for.
These issues aren't new; several years ago I had to ask the admin of another website to choose between making postings actively promoting their website over this one, or leaving. They chose to leave.
As to specifics, a particular issue with videos is that they often carry a series of promoted links in the 'about' section. Where these links are the sort we remove here, then we remove the video link.
Getting this right isn't easy and isn't always comfortable for us or for forum members – points I made when we were deciding what to do. But a policy has been put in place, and we now have to follow it. This has meant extra effort for moderation (especially for Jason) especially as the site has never been busier or attracted more new members (and spammers who have to be dealt with, usually invisibly to users).
Even so, I hope that in practice the impact on users has been relatively minimal and not detracted significantly from the site.
Since the new CoC we have actually had to do less editing than was expected, suggesting members are trying to follow them, and I thank members for that. Your patience and understanding is appreciated.
