Way of my thinking : #1
#SayNoToSuicide and #metoo,
one hash tag might be longer than another but both hold same worth and i.e. null. You can not simply stop harassment acts just by using #metoo and suicide by using #SayNoToSuicide. Better find the main root below every harassment and suicide, take them out together, and find something middle way to cut off such root instead of creating new hash tag trends.
