This is a common practice for me, I have alot of email addresses and thank goodness that email registeration is always free and take less than 5 minutes when bad network doesn't get in the way.
I have a special email address I use for signing up on gambling casinos and I make sure I never use that email for any other thing, I also have another email I use for social media platforms, and have email address I use for airdrops and so on..
Then I have another email which is my main email address that i use for very important stuffs.
This practise have helped me alot, as there was a time when the email address I used for crypto airdrops was hacked, the hacker gained access to some of my airdrop accounts which contained nothing, at the end, he found nothing to steal from me, now imagine I used that same email address for every of my online accounts, this would have turn3d into a major disaster for me.
Yes, that is right so that is what I did if I want to register on the casino. I always used a specific email address for my gambling habit so I could hide my email address from other things. We should separate different purposes of what we want to do because we don't know how long we can feel safe from hackers or scammers.
I used a different email address for crypto airdrops and not related to anything except for crypto airdrops. That allows me to manage all emails for different reason.
We should responsible and be careful with all things we want to do. We don't know who will trying to hack or scam us.
