Replytocom redirector plugin solves a problem with some bots that do not know how to handle the replytocom parameter as part of a wordpress url.
The Replytocom redirector is a really simple plugin coming to solve the problem of silly bots that scan the replytocom urls in a wordpress blog those urls have no value whatsoever for a bot as they contain duplicate content. even so - the bots keep scanning and scanning. In just under 9 months on our site we have had over 200,000 such requests, and it is not even a big site.Duplicate this by a minimal size of 10k of html code sent to the bot, and it seems like at least 2Gbyte of traffic was wasted for this nonsense.
This plugin solves the problem by simply redirecting such bots to the correct url, saving cpu, network resources and little bunnies.
If you ever encountered this and wanted to solve this, invest two minutes of your life and install this.
