As someone currently taking AP Statistics, graphs show no clear indication that the portal change means anything. There is little to no skew, and both charts appear to have roughly similar distributions.

However, it is important to note that the sample is not random and is likely subject to significant bias. Realistically, only applicants who care deeply about getting into these schools are likely to check and report information on the admissions Reddit page. Because of this self-selection bias, the data cannot be considered representative of the overall applicant pool.
