I was level 2 seller on Fiverr, And I send a text message to a pro seller and ask from pro seller how you got this pro gig. He flagged my account and Fiverr take my Level 1 and level 2 tags within 1 week. Now I cannot get my level 1 tag for 30 days.
Fiverr designed the inbox system to only conversation of buyer. So, Keep in mind, do not send messages to expect the buyer.
