I am curious. What would be the point of this?
Inflating follower count? Getting feedback from fellow developers?
While itch has some social media capabilities, it lacks direct messages/private messages. It usually is quite clear who wants to be followed (so you need not ask, and because of lack of messages, you actually can't). But those are publishers themselves, so them following you back by asking for it, is not really getting you more actual users, only a higher follower count.
On social media, "following" random people is a common spam and scam tactic. The spammer wants to attract you to visit their profile delivering their message. It is used like a ping phone call.
