Unfortunately, I’ve seen on some of these frum sites people posting under different catergories, not just one, like yeshvish.
And if you look at the picture, they don’t even look frum. Watch out -anybody can claim to be anything they want.
Since shadchunnus is a business, there are plenty in it for the money. And just like business people manipulate, lie, etc. to make a sale, so too will Shadchuhnim.
