Ghoster still liking my social media posts

I was ghosted a few months ago and I have completely disengaged on my end (took him out of my phone, muted him on all social media) but he's still following me on all social and liking A LOT of my posts, especially on Instagram. I'm guessing this is either a way to appease his guilt (see, I didn't ghost entirely) or a way to keep me on the line. Has this happened to any of you? How did you deal with it? Should I just go the next step and block him entirely? Did I mention I hate dating?
