In my cold audiences campaigns I'm excluding all the purchasers but I still see people who purchased commenting on those ads. The purchasers audience is relatively small (~200 people), could that be the reason on why Facebook can't really exclude them effectively?

There are a few reasons: 1) FB needs time to update the audience 2) They’ve purchased with a different E-Mail 3) people are using some filters to block cookies or something like that in their browser
