About

Indisposable is an application that helps protect your community by blocking registrations that use disposable e-mail addresses.

Why are disposable e-mails bad?

Disposable e-mails are not inherently bad, but they should not be used for registering accounts on platforms such as IPS.
Foremost, they present a significant security risk for your members. These e-mail accounts are publicly available to anyone and everyone with no password required. That means if someone registers for your community with a disposable e-mail address, anyone else who also uses that disposable e-mail service can see this and could completely take over that person's account.
Second, disposable e-mails are commonly used for abusive purposes, as they make evading bans much easier. Instead of the user having to go through the lengthier sign-up process for a new e-mail account with GMail or so on, they can generate a new throwaway e-mail in seconds.
