# Task Was Executed Too Fast

One PrimeLister account can be used on only one computer. "Task Was Executed Too Fast" error is given if a user tries to use a single PrimeLister account on multiple computers in order to post his listings faster. 

PrimeLister applies a waiting time between each posted listing for protecting seller accounts on Poshmark (US, CA, AU), eBay (US, CA, AU), Etsy, Facebook, Depop, Instagram, Facebook Marketplace, or Mercari and for mimicking a real human behavior. Please follow this rule.
