No.

When the first priority of a site is to collect my email, usually I'll have spam to manage for anywhere from a few weeks to many years. Whatever reason I have for visiting a site, it's pretty much never because I want to receive emails from it.

[generically] Email harvesting is a red flag for me. Watching the video before signing up, doesn't change that. It just means investing more time in a site that doesn't prioritize on it's users.

Some bars are worth paying a cover charge. Most aren't.

Good luck.
