Couple of things wrong with this:
1) A number of fellow voice actors and industry insiders have come out- first in support of victims, and then revealing they themselves have been victimized or witnessed creepy behavior from Vic. This isn't only congoers or fans coming forward, it's people who really know the guy.
2) RoosterTeeth has broken ties with him and Funi has replaced Vic in an upcoming dub with another actor. It's clear that at least these two companies think that the information presented is enough to choose to stop doing business with Vic. Perhaps they even have information we don't have (nor are we privileged to).
3) Filing charges for sexual assault or even non-sexual harassment long after the fact is hard, if not impossible. Consider that Texas's statue of limitations for sexual assault is five years, and sexual harassment is 300 days- if it's been that long since the event, it cannot be filed. Many other locales have similar statutes, and a lot of these stories seem to be at least that old if not older. This doesn't even get into the fact that research shows that many, many legitimate sexual assault and harassment cases are thrown out before they're even filed due to police choosing not to believe the victim or, in the case of harassment, that it "wasn't that bad", so if he did anything creepy recently, it's not unfathomable it'd never reach investigation let alone trial. Just because of the biases inherent in our system of law regarding sexual harassment and assault. So a lot of victims simply don't bother reporting, and even if they did, chances are nothing would come of it in spite of it really happening.
For this reason, public knowledge is as important in protecting people as the court of law. And the fact is, there are hundreds of people coming forward with firsthand stories of sex-pestery, or unprofessional or rude behavior... a good many putting public-figure-names to their accusations. Like, you can personally choose to think EVERYONE is lying (somehow), but the fact is, most people are going to see that Vic's got a lot of apologizing (actual apologizing, not shedding crocodile tears and giving a non-apology that puts the onus on his victims and subtly encouraging his fans to go after them) and growing to do, and that people aren't going to instantly forgive him until he's proved he can change- not that victims need to EVER forgive who's wronged them.
Yeah, a lot of fans have been heartbroken seeing Vic get outed (and Todd more or less self-out) like this, thinking that they "knew them", so the fact that people who actually spend entire weekends with them or work with him are discovering this must be even harder on them. I'm sorry you had to find out like this. And of course I feel even more sorry for the victims.
For what it's worth I agree that, while a list of people at cons to avoid is a good idea, the fact there isn't a lot of vetting going on and the individual hosting it is completely anonymous (not even a real username to speak of) makes all but the most backed-up named names worth taking with a huge grain of salt.
