When you look at the relationship that AggregateIQ had with many of the different campaign groups on the Leave side, and you see that all of those different campaign groups received donations—in some cases, very sizable donations—from Vote Leave, and that this money then all went to AggregateIQ, to me that looks like a proxy for breaking campaign spending law in the United Kingdom.
Facebook recently confirmed to The Electoral Commission and to the Parliament of the United Kingdom that in fact AggregateIQ had some of the same custom audiences and look-alike audiences that were based on their work for Vote Leave, for some of these other entities.
What has been established so far is that money went from Vote Leave to another campaign, and it then went to the same service provider for the same work that Vote Leave had. Facebook has now confirmed that some of the targeting and the target universes were exactly the same.
I don't know if calling it money laundering per se is the technically correct way of expressing that relationship, but in the general sense it does look like the relationship that it had with all of the Leave campaigns was to obfuscate electoral law in the U.K.
