+// @namespace   Reddit
+// @description Overwrites your Reddit comments to protect people from stalking, doxxing, and profiling you. Also, Reddit does not truly delete anything, but since they don't keep versions this better protects you. To use it, login to Reddit, click your username, go to comments, click on the OVERWRITE button. It is MUCH more efficient if you use RES and scroll to your oldest comment. If you are migrating accounts, you can move your subs by going to reddit.com/subreddits, and copying the link on the right.
