I recently uploaded a video to 3Speak, and this account asked me to verify my ownership of the video by placing Hive on my Youtube.

I find this kind of odd, and I didn't particularly like being asked to do something with my other account.

But here is a video I did on Youtube that features Hive, and has a link to my Hive in the description.
I feel this should more than verify I am who I say I am as it's a few years old at this point.
