There was a thread yesterday about a spellcatser who received a warning about empty deliveries. They had it removed though when CS was convinced that a spell promising to make the buyer a millionaire in 14-days really had been delivered.
Maybe think of targeting a new niche?
On the dropped files note, I rarely check anymore. I have noticed that if I go through my delivered orders, attachments are sometimes missing. Then after refreshing pages or waiting for a while they reappear. As it is, though, I’m not good with paranoia. I’d rather close shop than screenshot and video everything because of Fiverr bugs. - And it’s not like it helps. At least, not going off your last experience.
