Whatever floats your boat...
Hey, Gabriel, two things that are probably somewhere in the Ark's TOS.
1. If you post here, there's a minor risk of your vid getting sabovlogged.
2. If you post something bare of context, theres an elevated risk of it getting sabovlogged and having that context added. Said context may or may not be what you had in mind.
