Every model knows leak sites exist and it's not hard to find them searching your own name. It's usually a good idea to keep your usernames unique on different sites just as a precaution, but beyond that there isn't much to be done.
For Goose specifically I don't see reports or copyright letters or anything like that. If she is watching I don't think she cares much. Hell, some models I've talked to know they get traffic driven to them by sites like this. I've personally paid for stuff from models I've discovered on here.
