Minimal LinkedIn profile for discovery purposes is what I always had in mind - yet it got restricted several times without me doing anything offensive to LinkedIn, just using general privacy-enhancing measures.

The static link is a good idea!

But my question remains how I can prevent getting restricted. I have already had two profiles, with somewhat similar CVs, in one where I'm called John Doe and in the other Doe John (my name makes permuting these less obvious). So I guess I can't keep going like this, because at some point my entire name and CV will be tainted after too many restricted attempts. I need to get it right the next time, to not be restricted.

Regarding the legitimate communications: I am actually positive about this, because a big part of LinkedIn are connections. If I (somehow) manage to have an account that doesn't get restricted within weeks so that I can actually add my peers, I will have a number of high visible and important people endorsing me (well known professors and researchers). That should give my profile a lot of value, I think?

At the same time it would not compromise my privacy, other than that a part of my professional network is public - but that is public anyhow since it can be derived (with some work) my articles, so not much is actually lost.
