You did good.. do not post your pictures if you dont want to. If you’ll create a full “valid” intro post with pictures and signboards and videos and all, then at best you will get somewhat like 2$ or 3$ payout (5$ at best). After which, you will be like any other new comer, means earning 30 40 cents on each post until you build your reputation and SP to a specific level.. but the information and pictures that you will provide on your intro post will remain here forever..
so take it easy.. dont do it if you dont want to..
