This is a fair concern. There are a number of verification steps involved - hence the reason why the project had to push back the invitation e-mails being sent out. Every application receives individual attention. Most platforms today show an account creation date, and an application is more likely to be rejected if it's clear that the moniker that signed up cannot be linked to the URL submitted. This is why it is encouraged participants sign up with an online presence of some sort. There are also technical checks in place to avoid gaming the initiative. No system is going to be perfect, but reasonable steps can be taken to make it as inclusive and fair as possible.

Great to see people are starting to receive invitations and generating their addresses! The e-mails will keep flowing. Make sure you check your spam folder if you haven't whitelisted decred.org. There is also a dedicated support thread that just opened to help guide others through the process. Decred has an international community, so if you notice anything in the language-specific threads about getting help with the process, please help others where you can. You can also post here and people will help you if you have trouble.
