How Did You Find Me?

It is totally okay, tactful even, in today’s atmosphere, where almost everyone is active online and has something to show for it, to initiate a conversation with something along the lines of “I’ve seen you around.” You can mention whether you found them via a search or a share, or merely by scrolling/swiping, admit that you’ve been reading and/or viewing for a while and that’s why you eventually reached out to them, and go from there with further details about it. What caught your attention, what stood out for you, etc. All fine to bring up. At some point, could even point out if you noticed anything particularly peculiar and ask about it. It really isn’t weird behavior this far along.
