I’ve often wondered if something like this could be done with cookies etc. and wondering why it wasn’t done more often.
Anyone onreading this doing something similar (possibly in a different format). As long as it is in the T&C’s of the site signup it shouldn’t be illegal etc – or do the other companies maintain they “own” their cookies and therefore cant be touched etc.
Very interesting court case about privacy legal rights, T&C’s legal rights, cutting edge technology and data matching etc. Will be interesting to see how this one turns out.
