What Al is describing isn't comparable at all, we've never had issues with hot glue. Only the smallest dot is needed anyway. It doesn't flow, it's very viscous when hot.

Any chance you can send a picture of it "being applied as a little dab". I have always considered this a "best practice" to use a small dab of hot glue or RTV between the PWM connector and the housing to act as a anchor for impacts and shock.
That being said, when inspecting, I have obeserved several connectors that it was clear someone thought "more is better" and flooded the: CAN, PWM, Ethernet... connector. I typically see a couple of these per competition towards the end of the season. Often for an ethernet or JAG CAN that someone has brocken a tab on. Once the team gets to that state, they tend to have some sort of issue during most matches.
Googling "hot glue electrical connector" or "RTV electrical", I saw a lot of images of hot glue being used as some sort of conformable coating/filling which is not recommended for these connections.
