I have just had my worst Fiverr experience. New buyer ordered a site loading speed improvement gig for one website.
When order started, he demanded work to be done on 6 sites.
I decided to help him since he appeared to be kind and good person doing something for a good cause.
Then he started coming up with new demands, that I have to configure plugins and fix issues, that had nothing to do with my gig. I’ve helped him again, but he demaned even more fixes and additional work.
When I told him I will not do it, he started threatening me over my email (I had to register with my email on his site in order to check if login page is working properly, so he found out my email). He said he will write various comments about me in Fiverr community.
So my advice to everyone, be aware of new users asking for additional work… it might become never-ending gig.
