Thanks that was really helpful since it helps to clarify some things but I still have one more point which needs clarification.
How many registered user requests can call from the same IP address before their limit achieved?
A. 2 different OAuth users can have 350 authorized calls each from the same IP (i.e. Same IP - userA: 350 (limit userA), userB: 350 (limit userB)
or
B. 350 authorized calls per IP no matter which user called first. (i.e. Same IP - userA: 250 userB:100 = LIMIT)
thanks.
Updated: I’ve just found the following topic https://dev.twitter.com/discussions/3496 which partially covers me.
However I wanna ask some things… how can I contact you about my scenario?
