Linked-In has jumped the shark

It's time to recognize that all social media websites degrade over time, converging into similar crapified states that makes them pointless.  LinkedIn may have just jumped the shark and is headed into the downward spiral.

Today I received a sponsored message in my LinkedIn Inbox inviting me to find a love match at Selective Search Matchmaking (no link provided, intentionally). 

 LinkedIn, do you have no standards for appropriate sponsored content?  Shame on you.

There is an option to report undesired ads, but this is too little, too late.
