Actually, my logic for following is very simple: I don't care how many followers you have; the key is what you're doing, how you think, and whether you have valuable content.

For those who frequently interact with me, I usually go to check out their profiles. There was an account that initially interacted with my posts several times; I clicked in and browsed their content, and I found it really good, so I followed them immediately. Later, I found it interesting and even wrote an article to recommend them.

To put it simply—people with substance, even if they are low-key, can still be noticed.
