Wikitree does not delete profiles because it is a "relational database" built on the linkages between profiles, i.e. parent, chlld, spouse relationships. If Bradley-8241 is a bad version of a real person, he could be merged into that real person; then people looking for the bad version would be redirected to the real one.
However, since this came from Ancestry, it indicates that the bad version is already out there and we might well want to retain the bad version, with a suitable warning, to let people know that it is bad and why. This is the mandate of the Disproven Existence Project.
Once you are convinced that no such person as Bradley-8241 ever really existed, post a "Disproven Existence Notice" here on G2G. That sets a 1-week clock running which is really a challenge for the WikiTree community to find some documentation that would prove you wrong! Typically, they don't, and then we would put the Disproven Existence label on him. Since people who never existed never had parents, spouses, or children, we typically "quarantine" such a profile by removing any connections to others on WikiTree, although we put in links in the narrative so people who find the profile will understand what has happened.
