No. In some rare cases we do help users delete profiles from a GEDCOM import if they're very bad and we catch it within the first 24-48 hours. You uploaded your file last week so that's not possible. Other WikiTreers have been seeing the profiles you created and possibly seeking merges and starting collaboration. It's unfair to them to do deletions now. Instead, you need to move forward with changes.
