Well how do you define "actively participating"?
F1Fan commented a flaw in requiring one stream post here: https://imgflip.com/i/5xh0tv
So how about this: if a user has ever voted in a previous election, followed an IP-related stream (bank, DMV, ImgflipGovernment, etc.), and posted any content anywhere on the site in the last three days (to prove they're active) then they can vote. Is that ok?
