You'd have to know the amount of people who like posts to make an educated guess for how many subs somebody has.

But there are indicators that the amount of subs who like posts is quite low, in the <20% range:

I do think it's likely that the like-percentage is higher for somebody who is newer on the platform or posts less regularly. Both which apply to Bonbi.
