I recently received a mailing that gives me 2500pts per added user on my Chase Ink card. The user only has to make a single purchase by the end of March to have the points applied back to my account. The terms are not as detailed as many Chase offers, but do have a line "no limit to the number of pts you can earn with this offer". Wow is all I can say to that. Ink points transfer to Chase Sapphire, which in turn transfer to useful airline/hotel miles/pts.

Question is: For those who received this or similar offers; has anybody had Chase stop them at some point? Just wondering what other FT's experience with this odd offer might be.
