OMG guys the link OP posted youtu.be, not youtube.com! Watch oooout!
In all seriousness, from what I got from the thread, the suspicion was that the one link was ehnow and another was ehnw, which is a common phishing tactic (especially how the latter goes straight to an Apple Appstore listing). I don't think it was a direct attack on the legitimacy of Eh Now itself or you. Plus, people hate sign ups here because many, including myself, have been burned by centralized services. Which is why users here take a more scrutinizing position:
Wtf is Eh Now? Why make a centralized service when Mastodon is right there? What kind of people and company run Eh Now? How is my data going to be used? Is it even worth signing up to see a schedule to a protest I won't be going to? Why should I care if one famous "elbows up" guy endorses it?
I think these are all fair questions and I don't think you need to take it personally.
