I’ve got my profile still, but only log in every couple months. Every time I do, there are multiple requests from people I’ve never met or even heard of their company. I guess I’m just not into the “professional connections” since I just ignore. (Most aren’t even relevant to my industry)

Here’s another website that is a good directory/listing of Instances and Communities. https://lemmyverse.net/communities. I recommend using List View to see more at once.
