This is Yourls plugin use to skip spam check. in my case. i can't post ok-like.net url to facebook because facebook report this is spam, after i shorten link facebook report it spam too. so i this plugin use tag meta to redirect it will skip facebook spam check. if you want to redirect with tag meta add "_" (under score) before your keyword. if not it will use header redirect as default.
- In /user/plugins, create a new folder named meta-redirect
- Drop these files in that directory
- Go to the Plugins administration page and activate the plugin
- Have fun
if you want to try it. i installed this plugin as tey.me Develop on Yourls 1.7
