For now, sure. Reddit was one a place of free speech and only removed illegal content. But look at it now. See where I'm going with this? If you want something long term that lasts, you have to accept the good with the bad, and ban no speech at all. The people who abuse it have to be held accountable individually for any crimes they commit. The problem though, is that the law enforcement wants to cry that if we "just gave them access" through a backdoor, or if these companies would reveal this information on the offender, it would make their jobs easier. That's not a good enough excuse. Do your job - do the leg work, catch the bad guys through hard work. Regardless of the amount of illegal / undesired content you have to deal with, it's still not worth providing this sort of restriction at the risk of infringing on even one person's right to free speech. This is precisely how we get where we are today.

It's no different than the 2A argument. You can't just ban all guns and expect that people who seek to do harm to others won't find some other way to do harm, or obtain a gun illegally (which they almost always do anyway - or it's just the FBI/CIA doing what they do to create a problem-reaction-solution situation).
