I have been using downforeveryoneorjustme.com the correct site for ages and I don’t type the URL but use the one I have as a bookmark. Most commonly used in conjunction with the forums at times.
That said this isn’t typo squatting as it is completely different not some accidental typo (transposed character or mis-speling) it is completely different.
I honestly can’t see why you have posted this anyway, typo squatting (even if this isn’t really typo squatting) is nothing new and considering that avast actually protects against this alternative site it is a bit of a non-issue. Not to mention the real site isn’t an issue either as avast doesn’t alert.
