That's not even a boomer complaint. Zoomer here. I fucking hate how everything needs an account. I recently started cleaning up my mail box and this shit makes that nigh impossible. I especially hate it when it's just a shitty novelty site, if it needs an account, you bet your ass I ain't ever using it, piss off!
make an email for different things, such as one for subscriptions, one for things like this, one for professional use, etc. it's annoying but also helps 🤷🏻 i hate that we're at this point lol
My trick is that I use a domain name I've bought for my personal emails which is a catch-all address, and I sign up to websites with "(websitename)login@domain.url", so I'm assuming I'll know who the culprit is when the time comes and I can do something about it with relative ease. I don't know if that's actually smart or not but I'll see how I get on.
I do the same and use simple login as a service to manage the emails. They all get forwarded to a single mailbox, but I can easily activate/deactivate individual addresses. Also, I have all incoming addresses blacklisted by default, unless they match a particular regex. That way, I can create new email addresses as needed without needing to pull any levers, but im still protected against someone spamming my domain (unless they figure out my regex)
