It doesn't. It is 100% free - as in speech. All services here are provided under the "pro bono" banner - see the definition of that below.
Pro bono publico (English: "for the public good"; usually shortened to pro bono) is a Latin phrase for professional work undertaken voluntarily and without payment. Unlike traditional volunteering, it uses the specific skills of professionals to provide services to those who are unable to afford them.

However, as with all things free, there are always limits, and realistic expectations. These are outlined in the Usage Policy
Since inception, this site has proven to be quite popular, and that's a good thing of course. However, with that popularity comes the unwanted creation of spam accounts that are designed solely to provide backlinks to other sites via the profile page, or to simply post meaningless content into random topics.

As this site has increased in popularity, so have the spam registrations. In order to keep the platform clean for everyone requiring assistance without having to trudge through hundreds of spam posts, we took the decision to individually check and validate each registration request.

This is not a decision we have taken lightly, and we hope you understand the genesis for doing so. We think that waiting for your registration to be approved in contrast to being bombarded with junk that only serves to dilute the reason this site exists in the first place is a small price to pay.

Absolutely. We don't even ask you for your name when you sign up, and the email address you decide to use is entirely up to you. We only store essential information that is required, at a minimum, for the site and associated services to function (for example, login, registration, notifications).

We promise to
  • Never bombard you with unwanted ads.
  • Never reveal your email address (unless you choose to do this yourself via the profile page).
  • Spy on your browsing history.
  • Send you unsolicited email without your consent that you have not explicity requested.
  • Permit access to or sell your data to anybody.

If you want to register using a pseudonym, then that's absolutely fine with us. You can find more information in our Privacy Policy.
Good question. First, let's remember that security isn't a product. It's a framework - a selection of best practices, common accepted industry standards, hardening, and a variety of other "hidden" techniques and technologies that form the basis of the overarching security model that sudonix.com deploys. We are committed to the security of personal data. We take appropriate security measures to limit abuse of and unauthorised access to personal data. This ensures that only the necessary persons have access to your data, that access to the data is protected, and that our security measures are regularly reviewed. The security measures we use consist of:
  • Username and Password.
  • DNSSEC.
  • TLS / SSL.
  • DKIM, SPF and DMARC.
  • Physical security measures of systems which contain personal data.
  • Security software.
We have an immense dislike for ads, and if we don't like them popping up all over the place, what gives us the right to expect you to put up with it? Besides, wouldn't the internet be a much better place if you weren't forced to use a popup or ad blocker every time you used it?

In the same vein, this site does not rely on sponsorship - nor does it generate revenue, so there is no need for any advertising of any kind.
