Absolutely not!!! Just NO!
Experience 2 days ago on FB...I linked to a story about a family who lost their pet. The story was on a local news website and there is not one ad on the web page. There was no ad on that page before or after I linked to it.
In FB where I posted the story to my wall in case any local friends had seen the missing pet, the picture of the pet was NOT present and FB had inserted an ad instead. That ad would not go away and reposting it brought the same ad. Some people who had also posted that story had no ad and only a picture of the dog. My post and some others' identical posts had the ad inserted instead of the picture.
Disgraceful what they'll do for advertising revenue. No thanks FB...perhaps my FB account will be closed due to so many different security concerns soon anyway. I don't post anything I care if people see or not, but I get angry when my post is altered without my knowledge or consent.
