Someone in my College made a petition to suspend everyone who has been accused of sexual misconduct

A girl in our second year accused someone, but the legal system will take 6 months. So she started this petition, with the goal of getting everyone accused suspended until a verdict is reached. It seems mainly geared towards this one guy, but the title and text still call for all suspects to be suspended.

In the groupchat of my year people are angry, calling for suspension even though no proof has been shown yet. People seem to have done away with the principle of 'innocent until proven guilty'. I want to support victims, but this just seems crazy!

On top of that, one of my best friends had also been falsely accused by a different girl (weeks before). He is having a breakdown, his depression making a swift comeback because of the accusation. I truly believe he is innocent, they hooked up multiple times, she was sober and they even showered together. But she had a boyfriend, as he found out later, so possibly she didn't want to own up to it. He has moved out of our building already on request on the uni, but still studies with us.

What can I do to ensure people aren't getting suspended based on accusations alone? Is a petition like this even legal? I am personally rather upset by the amount of ire this has elicited. When I defended maybe not punishing someone without evidence I got some angry comments thrown my way.

EDIT: I want to put this into perspective, there is no physical protests or anything going on, just discussions in the groupchat. However, the petition now has 681 signatures. I assume most of them are just out of solidarity, but the title of the petition is ''MY UNIVERSITY to Suspend Suspects of Sexual Crimes from Education'' so it isn't exactly covert in its intentions. It is only a petition, but still.

There are people speaking out against this luckily, so it isn't as bad as it could be.
