Mr. Sen mentions it a few times in his videos on Rev Says Desu that Rev flags videos that show him telling his discord server members to harass users on Twitter. This was before the pre-RevDox arc.
I should probably mention Mr. Sen outright lies about shit, and scrolling through his video nothing I saw showed him telling others harass people.
I could've missed it but I watched this video two times to make sure and nothing.
Onto Sen's habit of lying.
He originally admitted those leaked ERP logs were real then that they were faked despite saying they were real then that they were fake and that he was blackmailed into pretending they were real.
It's four hours but these guys actually invited Sen over and show this.
He has a record of throwing people under the bus whenever it falls back onto him.
