I am a PM with LinkedIn. DM me and I can try to funnel this to the right channels. I'll be the first to say that there are a lot of problems with LinkedIn, but the company's "heart" is generally in the right place.

We shouldn't be punishing the gear on the cog that is helping turn the machine in the direction it needs to go.
