The reddit post
seems short enough but I'll tldr anyways:
1. dude gets a junior (girl) drunk and keeps asking her if she likes him, and after getting suspended he even went around telling people she liked him. very much harrassment
2. various malicious and cowardly acts towards committee members when being an exco of the committee, painting them as inadequate (hid meeting from members and then attended meeting blaming them for not turning up) when he was the one who MIA for 5-6 months and did not organise things despite being the in-charge.
3. NTU handled harrassment case poorly by giving harrasser slap on the wrist (3 month suspension), gaslit and victim-blamed
