I am sure it will be taken down after it gets put up because "The Internet doesn't forget" and people will spam it and all so. I agree, and most people would, but the thing is that pedos know the game and can blend in well to fit in since most social platforms don't require any proof or anything, and of course if they did that would be a whole another can of worms.ffs...
There are a lot of issues with the internet right now and these "social platforms" but one thing EVERYONE should agree on is that pedophiles should not have the opportunity to have interactions with minors online anywhere. If there is a site that allows people under 18, they should not be able to make accounts on those sites, period.
