Overwhelming with garbage data is definitely something you can do with social network trackers, it's definitely something I engaged in when I was most active on Facebook. That said it seems to me the far better solution, if you actually value your privacy, is to give up the convenience it would offer and simply not let systems like this into your house.

In a fight to protect your privacy, the only way to win is to not willingly give up your data, even if that means not making use of new systems or taking active countermeasures against tracking systems.
