The 15 nodes shown below are corroborated with documentation and credible testimony. This is not an exhaustive list of every data gateway and relevant flow, but I do remain confident in stating that this is a reasonable depiction of what has transpired.

AIQ harvested, and attached to profiles, the Facebook IDs of registered UK voters who had a Facebook account. This data was all synchronized (matched together from many data sources) and collected through the platform offered by Nationbuilder.com. […] I have the synchronization scripts showing the aggregation on that platform as well as the names of databases controlled directly by AggregateIQ containing this data (along with the usernames and passwords to access the databases).
