I respect the right of everyone to choose for themselves. I do not like it and I should have the right to stop them. On their site, they offer those who do not want it the choice, saying, "make a comment with just the word STOP and we will stop posting in all your posts." I used STOP on all 3 of my accounts and they ignore it, continuing. After asking them to stop a third time, I decided to flag them (if it affects the money-wise, maybe that will make them re-think).

Otherwise, I am against flagging and only do so on a tit-for-tat basis (and reverse mine as soon as I get an apology or they reverse theirs).
