Lightbeam
Iâve recently been trying to figure out how the LinkedIn People You May Know anti-feature seems so sketchy in the data itâs pulling from email exchanges and accounts that Iâve never specifically linked to the site. Apparently the LinkedIn mobile apps will rip your entire contact list, and even if you donât use these apps, it appears to somehow reverse-link the rest of us (based on real names, not email addresses) from the suckers who do. There are some ongoing attempts to try to get this pulled in, but LinkedIn doesnât appear to have done anything illegal so far, rather has just been sneaky in making excellent use of the EULAs and app permissions notifications that everyone clicks through without reading.
Anyway, Lightbeam/Collusion is a Firefox and Chrome plugin that will illustrate how many other entities are putting their fingers in when you visit what may seem like an unrelated site. From what I can tell, LinkedIn isnât illicitly directly connecting to Gmail or any other contact services. Thanks for the heads up TJ!
wikipedia:
Lightbeam (called Collusion in its experimental version) is an add-on for Firefox that displays third party tracking cookies placed on the userâs computer while visiting various websites. It displays a graph of the interactions and connections of sites visited and the tracking sites to which they provide information.
