I sent Depositphotos my portfolio of ~1600 images via their "High volume" contributor service. A few days ago, I tried logging in to check my earnings (I'd already received one payout, after I got 3 high value sales within days of the first images going online). I immediately got the error that my account has been "blocked" and to contact support. I did, marking the request "high" priority.

That was Thursday... no reply since, and my account is still blocked!

Has this happened to anyone else? What was the cause?

Is there anything I can do to speed up the time it takes to get search results? Use a specific web browser...?
