Took the words right outta my mouth. She probably just needs a couple hundreds dollars for the current thing she wants so she's going to post 1-2 pictures over the course of a few months, get her money, then take the stuff down and change names until she needs money again.
I don't keep track of it all the time but on Mar 11, she had 34 posts, 26 pics, and 3 videos, Mar 18 she had 35 posts, 27 pics, and 3 video (okay going up as it should), then today she has 34 posts, 25 pics, and 3 videos... so she's deleted stuff.
I also had a good laugh at IG telling me that (just on the one account) she's changed her name 5 times already.
