Website question

Hello,

Under some videos in the comment section, there are video titles where the 'member name' usually is with short blurbs. When I hover these links, they show they'd link to like 'studioveena1.com' or 'staging.studioveena'.

I just wanted to verify if these are legitimate links as they look a little out of place.

For example, here is a screenshot under the pole hold tutorial.

Thanks!
