This rumor was posted on SJMR. Does the accuser have links to the relevant tweets? This has legal relevance.
If this accusation is true, then Shamus is a sexual abuser who flaunts his own predatory behavior and chooses to make it his "identity" presented to students.
Someone posted this earlier when they were defending Ben H. Car/rington (a.k.a. "the Ultimate Rape-Bro") who posted photos of himself on twitter with a p/*/r/n performer he was paying for s/e/x and even managed to get some of his students to also retweet her account that contained explicit hardcore images.
Ben deleted his twitter account after his history of harassment was exposed, going the Way of the Groll.
If the accusations against Shamus are true, he's no better than BHC or EAG, and would need to be removed from academia by any means necessary.
Remember that feminists protested against Clarence Thomas for inappropriately discussing p/*/r/n and telling s/e/x jokes in professional settings. So weird that the people pretending to be "liberals" in soc openly broadcast the same behavior. It's like feminism was entirely raped apart after the year 2000 and the anti-feminist rapemonsters seized it as their own label. Even Buggs, the notorious abuser of students, calls herself a "feminist."
