I’ve finally managed to count them with the script I’m coding for deleting the eldest ones and it seems that they are exactly 100. I don’t think that’s so “abusive”*…
This answers my main question in the thread… so remains the suggestion.
(If anybody knows where to send this kind of suggestions in addition to this forum, that would be great. Thank you)
PS: I’m receiving a “next_cursor” parameter althought there is no more collections to list. (this contradicts the API documentation, so I think that it might be a bug)
*EDIT: I want to clarify this.
I don’t think 100 collections is abusive(althought perhaps “illogical” if you can’t imagine an app like mine) because:
They don’t give any notifications, so no spam can be actually done.
They are associated with the username(username/timelines/IDofcollection), so I can’t see, from my point of view, a “scalability” problem there. (perhaps I’m mistaken)
