Are any of those official successors?

Just about any defunct online service sees a dozen knockoffs of even more questionable quality than the original (for those into manga, think what happened to the site batoto after being sold). But it still remains that if you go to omegle.com, you get the defunct page and an explanation. Typing it into search engines did give exactly one that I know is legitimately a chatting service (ome.tv), but also are trying to act as if they are the original sites, some seemingly using templates and pointing to different apps to direct download their apks and the like.

I think suggesting they're the same as the original (which was grimy, and full of sex pests, but the site itself didn't pose such blatant infosec issues) is disingenuous imo

It doesn't work. I've tried all the "restarts" they are either faulty in a sense of the don't work or they are dead and no one uses it anymore. It was shut down in 2022. The others are clones but I haven't found one that works for me or has anyone on it. It's dead.
