Could mining vanity npubs turn into intricate impersonation attempts? like my npub is npub1hte85nxymfyez0nlmmxf287nh9cujfuetxhk9vptwcdqg0pn8pxqxasw3d but it abbreviates to npub1hte85nxymfy:dqg0pn8pxqxasw3d. could someone mine an npub that has a similar abbreviation?

If I’m correct, npub1hte85nxymfyez0nlmmxf287nh9cujfuetxhk9vptwcdqg0pn8pxqxasw3d and npub1hte85nxymfyxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxdqg0pn8pxqxasw3d both abbreviate to npub1hte85nxymfy:dqg0pn8pxqxasw3d

This could be a non-issue. Just thinking about newcomers and non technical people like myself that may overlook actually checking the whole npub
