What's the solution then? I see people suggesting photos with signs, but I definitely do not think that's a good idea. For people who have other accounts, I think linking back to the steemit account from them is the best, right? Maybe there's another way?

I guess the bottom line is that if you are already a famous person, verifying using other social media accounts to link back works. Then for anyone without those accounts, perhaps verifying isn't as big of a deal. They can get away with more easily faked verification options since not as much is at stake?
