I hate to suggest this, but 4chan's /v/ and /b/ board would bring a lot of people, 4chan has a very high number of visitors AFAIK. I know it's full of retards now, but the casual retards will stay a few days and leave.also 8chan is the place where people from 4chan went after it turned SJW, they have a /v/ board too. I would post there, but I leave that to the professionals.
