The biggest month: 136 valid reports across 61 programs.

September was the biggest month yet.

136 valid reports across 61 programs, with eighteen critical and forty-seven high.

I passed through Booking.com, TikTok, PlayStation, AT&T, Expedia and Superhuman, among others.

136 valid in a month, without the quality slipping, is among the best the series has given me so far.
