In another post I mentioned in one of my comments the possibility of making accounts in commenting sites (like Disqus) with disposable email services…
One of them is Guerrilla Mail, probably the best. It has several domains, so, if the @guerrillamail.com domain doesn’t work, you can try with another. And you can send emails with it too, although it logs your IP and sends it to the receiver of the mail (so to prevent abuse, spam, etc). But you can circumvent this very easily. Just use a proxy, either manually configured or via TOR browser. It will show up the IP from there. Always check your IP when you are using a proxy or VPN, so you know that your spoofed IP works or not. If it shows your real IP, change your proxy. With TOR you don’t have that problem…
You have to bear in mind that the incoming emails are stored for a very limited lapse of time. Only one hour. So check your mail quickly if you are expecting something important!
Guerrilla Mail has an app published for Android, as well.
The Android app has the advantage of being capable of sending notifications when a new mail arrives. But you can’t send mails through it… at least, not in a free way. You have to purchase credits first.
Other disposable mail service is Mailinator. Its storage lapse is greater. Mails are kept in the server for 24 hours (opposed to the single hour of GM’s quarantine. Notice that Guerrilla will keep the mail for one more hour after the user checks his inbox. Then, it will definitely delete it!).
You can also make an user on Mailinator, so to save interesting emails to your own personal inbox. And you can use Guerrilla Mail to register, too.
You can pause the stream of incoming mails so your inbox doesn’t get flooded with too many emails, etc.
Both services feature several domains (so if you get barred from registering with one domain, try another).
Bear in mind that Mailinator is a receive-only service, as opposed to GM’s sending capabilities. Also, Mailinator doesn’t have an app on neither mobile OS (no app for Ithings, nor Android). But if one really, and I stress this, REALLY wishes to get mails via other means that are not the website, you can pay for having access to the API. But this is a bit overkill, honestly, unless you are expecting a REALLY big quantity of emails (if you check the pricing section you can see the other perks the plans unlock, and all of them are a bit expensive). For a few mails, is not needed.
Both can be used to register in sites that let you comment, like Disqus. Heck, you can even use Guerrilla Mail to register in Failberg as well! Bear in mind the limited time that it will store your mails, and, if you can, download the Android app for it. The notifications can really be a life saver when you want to not miss any of your mails!
Or you can use another Gmail address, another Outlook address, another Yahoo! address, etc… But having to register ANOTHER mail in any of the above mentioned because you are banned from X site because you kicked a SJW in the teeth (metaphorically, in reality you just made him look like an ass and they banned you!) is just too cumbersome! To use both of these services, no registration is needed… Obviously, since you don’t use passwords, every mail can be seen (if you know to which inbox it goes into!)
Also, Guerrilla Mail is more TOR friendly than Mailinator. Mailinator, if you access the site from the TOR browser, it will ask you to complete captchas, unlike GM.
Please bear in mind that I mention these services because I use them (so I know them). If there are similar services that allow you to do the same, please tell me so in the comments.
Also, DO NOT expect privacy for either service, due to the above mentioned. The mail addresses are PUBLIC, so anyone can read them. But since you don’t really care for whatever are you going to receive, because you know it’s spam or whatever, that’s not really a problem. Besides, it gets deleted fast.
