Maybe the endgame is honesty. Not pretending you're several people, or other convoluted ways of misdirection and disguise.
Just honestly acknowledge that profiling exists, and explicitly work against it.
That should be enough to make any algorithm company that notices something is wrong to trip on its own wires, thinking some more elaborate form of hackery/covertion is being employed.
The likelyhood of some company noticing a single user is quite low though, but if you are able to hook even a single person inside that company using nothing but honesty and no tricks, that is the best trick of all.
