This is the reply I got from Support:
I have checked your account and your Gig "copyedit your text to make sure it is free of errors" and found that it has been created for the purpose of editing dissertations, papers, etc...
Due to this, as academic services are not in accordance with our guidelines, your Gig was denied and we will not be able to restore it.
However, you are still welcome to create a new Gig that is in line with our guidelines, which you can find in our Community Standards. If you are not sure if a service is allowed, you can reach out to us and we will check it for you.
Copyediting a dissertation for grammar, spelling, punctuation, etc., is NOT doing the author's work for them. It is a legitimate activity that does not violate schools' honor codes.
Can't restore the gig. Guess I'll start a different one.
