What happened? I'm seeking a dissertation editor. I. upgraded in order to send more invitations. Upwork took the payment then immediately suspended my listing. I do not understand what happened. Who can help me?
I believe your job posting tripped some automated keyword-based filters in Upwork's system.
You may need to re-word your job posting in order to avoid triggering those filters.
I suggest trying to explain your need for an editor by describing the topic of the work that will be edited, rather than referring to a "dissertation." Upwork does not want clients to hire freelancers to do their homework for them. If you can re-word your job posting in a way that doesn't make the automated filters think that's going on, you may be able to post without any problems.
