Please. Captcha by default. Email domain filters. Auto-block federation from servers that don’t respect. By default. Urgent.
And yes, to refute some comments, this publication is being upvoted by bots. A single computer was needed, not “thousands of dollars” spent.
Correct, Gmail essentially doesn’t “see” dots hello@gmail is the same as h.e.l.l.o@gmail
hello+anything@gmail will also be delivered to hello@gmail. This is great for signing up for mailing lists or subscriptions then creating a filter afterwards to do with it what you please.
There’s one exception to that. If you originally created the email address with a dot in it, as in, signed up for gmail as “[email protected],” it’s treated as a literal character in the username portion and is required.
It’s still not required in this case…
Then that has changed at some point. Used to be that if you registered it with a dot in the name, you had to always use that dot.
This particular quirk can be easily accounted for tbqh.
