I’m sorry to hear that is happening to you. Fiverr will take a while to get back to you. On average it takes around 3-5 days for them to respond to me, but it may differ for you.
Anyway, keep an eye on them. Fiverr will ban their gigs if Fiverr sees them stealing content. They will probably be banned. I had a similar situation here over 5 years ago. I have a forum posting gig, and I work with a lot of other forum posters. So, I caught this guy copying my content word for word, not even changing it or anything. What this guy would do is, he would copy my posts from another forum, and post them on another forum they’re working on. This is how I caught the person. I told Fiverr and they removed the guys gig.
Funnily enough, I caught the guy posting in a topic about users losing their gigs/seller status, and he comes in saying he didn’t know why lol. I ended up responding to that post, but he never replied.
I actually caught another seller recently copying my posts, as we were both working the same forums. It’s easy to catch when they copy/paste and change nothing. I was able to talk to the guy and told him to cut it out, otherwise I’d report him to fiverr. I told him he can take ideas from my topics, but he can’t outright copy/paste. He’d have to make the posts his own, in his own words. I’m cool with that. Just don’t copy my work, that’s all.
Anyway, sorry for posting this wall of text. Keep reporting the profiles as you see them. They will eventually be taken down. Here’s hoping fiverr moves fast here.
