I’m in business to get orders, not messages. You’re confusing Fiverr with other competitors.
Why are you on Fiverr? Why do you like messages so much?
I don’t understand sellers that get offended if I order without messaging them first. I would understand if the project was controversial, but if it’s not, what’s the problem? Besides, why should I wait for the seller to get back to me? Why should I check “online only” and limit the talent I can get?
I suppose some sellers would love to be on camera, chatting with buyers, but that’s not Fiverr. We should all learn to work within Fiverr’s parameters. We can always suggest improvements, but in the meantime, adapt to Fiverr instead of expecting Fiverr to adapt to you.
