Did you go ahead and update your profile? I can't tell you if you've been temp suspended, but can tell you that in my experience what you've described is not unusual. I've been pretty active on e-rewards for years, and I still periodically get a "No available surveys, please update your profile" message. Sometimes it's a couple of questions, and every once in a long while there are a bunch of categories that require updating. Typically they've added one or more questions to a category that had already been completed. The old Q&A are still there but some new questions are waiting to be answered. I take a few minutes, finish answering the new questions, and then wait for a new round of surveys to appear, typically no later than the next day.
