+# rfd-redirect-stripper
+
+This is a [Tampermonkey](https://www.tampermonkey.net/) userscript that strips affiliate redirects from deal links posted on https://forums.redflagdeals.com.
+
+## Why?
+
+This can help prevent broken links from collisions with adblockers. I wouldn't suggest using this unless you are experiencing difficulties opening links. Affiliate links and referrals help support RedFlagDeals.com.
