You are 100% correct. I'm still trying to figure things out. I swear I saw on one platform the link embedded a video in the comments, and did not realize YT vids automatically embedded without adding additional lines of syntax in the primary post.
I try not to link things that are easily searchable as a blanket rule in crypto, but I think that tendency is not necessary here.
Cheers
Edit: on SPT platform the linked video is embedded whereas on Peakd it is not.
