Well, it’s going to be a pretty short story, since TOS means you can’t have more than one account. That said, you could write to Customer Support and explain that you didn’t realize you needed to enable vacation mode (which is only two weeks, and I suspect your away period was extensive), You didn’t, so that great account is probably dead under the weight of auto “order canceled!” reviews, not to mention not having any sales in the intervening disabled period.
As a business, Fiverr should have done what they did–buyers coming here expect seller accounts to be live and deliver a product that fits the gig description, and on time. To let inactive sellers continue (whether on vaction without notification, death, awful accident, horrific natural disaster that affects your country/region for months on end) is not going to work. I am pretty sure that Fiverr would make an exception if you could prove your absence was entirely out of your own control (in particular natural disaster–who wants to be the evil corp that punished someone who’s struggled through a Nepalese earthquake, for example? OF COURSE THERE’S NO BLOODY INTERNET AND I’M TRAUMATIZED AND DON’T WANT TO MAKE A $5 LOGO!)
If you just went on holiday to relax or you had no internet at home and didn’t feel like going to your local internet cafe, then… nah man. This is business. You need to make it clear you’re going to be away for some time. Vacation mode is there, and there’s even workarounds to keep it going! Of course, you will lose your gig ranking, so better just to keep working while making all your gigs super-expensive and delivery times to the max. Which will also affect your rankings eventually. So, just be a good little worker bee and take your work where you go.
Anyway, let’s move onto part 2, shall we? Unless you have a really good reason here, you’re starting again (illegally under TOS) because you didn’t treat your job here like a real job.
