Interesting, I'm surprised to hear that this happened. In my recollection, most of the mentions of "voter suppression" had to do with things like voter registration shenanigans, not so much political ads. And voter registration shenanigans are definitely voter suppression.
AIUI Trump supporters used targeted facebook ads to go after American Haitians to remind them of the Clinton Global Initiative(which has a very bad reputation on the ground in Haiti).
