-If you have a feature suggestion for EssentialsX, read the following tips:
-
-1.  Fill out the template.
-      This will help us understand what you're requesting and why you want us
-      to add it.
-
-2.  Keep it simple.
-      Make sure it's easy to understand what you're requesting. A good way is
-      to keep it to one request per GitHub issue, as we can then easily track
-      feature requests.
-
-3.  Check whether it has already been asked or added.
-      You can search the issue tracker to see if your feature has already been
-      requested at https://github.com/EssentialsX/Essentials/issues. You can
-      also check the changelogs to see if the feature was recently added:
-      https://github.com/EssentialsX/Essentials/releases
-
-4.  Ask yourself: "Does this belong in EssentialsX?"
-      There are lots of features that we reject because most servers won't
-      need or use them. If your feature is very specific or already exists in
-      another plugin, it might not be a good fit for EssentialsX.

+     * This migration cleans up unused files left behind by the chaos resulting from Vault's questionable economy
+     * integration, and upstream Essentials' rushed and untested 1.7.10 UUID support.
+     * Both of these have been fixed in EssentialsX as of 2.18.x and 2.19.x respectively, but the leftover userdata
+     * files can reach into the tens of thousands and can cause excessive memory and storage usage, so this migration
+     * relocates these files to a backup folder to be removed by the server owner at a later date.
+     * <p>
+     * To quote JRoy, who suffered immensely while trying to debug and fix various related issues:
+     * <p>
+     * "Essentials decided when adding its initial support for UUIDs, it wanted an implementation which would cause
+     * eternal pain and suffering for any person who dared touch any of the code in the future. This code that was made
+     * was so bad, it managed to somehow not maintain any actual UUID support for any external integrations/plugins.
+     * Up until 2.19.0 and 2.18.0 respectively, our Vault integration and entire Economy system was entirely based off
+     * username strings, and thanks to Vault being a flawed standard, for some reason exposes account create to third
+     * party plugins rather than letting the implementation handle it. That doesn't seem like a huge problem at the
+     * surface, but there was one small problem: whoever made the Vault integration for Essentials suffered a stroke in
+     * the process of creating it. The implementation for the createAccount method, regardless of whether it was an
+     * actual player or an NPC account (which the Vault spec NEVER accounted for but plugins just have to guess when
+     * to support them), it would always create an NPC account. This caused any plugin integrating with Vault, creating
+     * NPC accounts for pretty much every single player on the server. It still, to this day, amazes me how nobody saw
+     * this code and didn't die without rewriting it; Or how everybody simply didn't stop using this plugin because how
+     * awful that godforsaken code was. Anyways, this upgrade does its best to delete NPC accounts created by the
+     * horrible economy code, as any operation which loads all user data into memory will load all these NPC accounts
+     * and spam the console with warnings."
