Shareaholic Related Posts functionality is broken as a result of Simplero rate limiting/blocking Shareaholic content indexing bot.

This is a well behaved bot that is whitelisted across the major hosts, etc.
Ironically, if the bot was not well-behaved and used throw-away IPs and non-descript UA's, Shareaholic wouldn't face this issue! But that is not the way.
