That sounds impossible even for one language. A better description I might trust wouldn’t include “filter out”. Filter out!? Like activities that aren’t “filtered out” would somehow be blanket acceptable?

Wouldn’t it be easier to just use an FB api to send one ping when a transaction completes, e.g with a campaign ID? Why would fb ever be uploading what’s stored in a form field that they don’t know what it means? It makes no sense?
