To me, it doesn't feel forced at all - it's up to me whether I want to contact the suggestions, or ignore. Often times I get a suggestion for someone who I've spoken to recently, and I can happily ignore the reminder!
The biggest issue I have with it is keeping the contact list up to date. I would love if someone built software that did exactly this, but also let me sync my Linkedin / Instagram / Gmail accounts and suggested new people to add to my list, based on who I've newly connected with recently. Or if there's a way to do it in Airtable, even better.
