misinformation in social networks is what is done once a 
message (tweet, FB post, etc.) is identified as a problem.

Many social network platforms like Facebook, particu-
larly those located in societies which emphasize the impor-
tance of freedom of expression, may feel uncomfortable 
outright banning or censoring posts (Kang and Isaac 2019). 
Instead, flagging posts from a questionable source or flag-
ging information that is known to miss what credible sources 
are saying is a common approach. Yet, does flagging misin-
formation or a questionable source sway social media users 
if they already believe the information being flagged?
