As someone who commonly has other people mistakenly use my email when signing up for things, I 100% blame the service (Netflix) for this. This is only done as a way for them to increase signups/revenue and the fact that so few services require verification is why people don't realize they are using an email that isn't theirs for years. Getting rid of dots only solves one tiny portion of this problem which would be completely solved if Netflix and others required verification. Gmail cannot stop people from using my email address to sign up for things, but Nextlix et al. can do that and protect their users privacy and personal info with one single email. A better example is that a few years ago Turbo Tax emailed me personal details and gave me access to someone else's taxes because they didn't require verification. That is insane (and I believe/hope was since fixed)!
