That was my initial question too, but note it's per oauth application. It could be that per-user it could get under 100, but in aggregate the only way they'd get there is if only one person used Apollo at a time.
I wonder why didn't Apollo just have each user register a new OAuth app at https://old.reddit.com/prefs/apps, the details of which would then be used per-user. It could even be done automatically upon entering one's credentials into the Apollo app. Wouldn't this have solved the problem?
Probably because the Apollo dev was sick of this shit and just wants to be done, especially after being slandered by the CEO of the company
if you assume that reddit won't just ban or at least take API access away from any user doing that, sure. I would not assume that.
