Pop-up blockers need to be disabled! If the chat window fails to open, or is non-responsive, use a different device to start the interaction.

If you are a contributor, then yes, your contributor account can be blocked for multiple reasons:

• posting assets that are not yours
• excessive sales activities, showing some kind of fraud pattern
• spamming the submission queue 
• submitting inappropriate content
• having submitted massively content that does not meet the required quality (this are mostly older accounts of people, who submitted prior to the stringent vetting that Adobe applies).
