I once delegated the little vest I had to upvu when it was newly launched on blurt but had to withdraw after the strong debate between many community members over the dangers of vote buying services. So I believe I have a little idea of what's happening now in blurt
I always knew Blurt just like other social media dApps will face the challenge of voting services once it grows in popularity and value and there is very little resistance being but in place to reduce its effect on other users not using it.
The only way to balance such structure is to create strong community accounts and other voting accounts for content creators so that the freedom of everyone can be respected and smaller accounts like myself can be encouraged.
