I upvoted this post because I know and I trust you, but I totally understand @innuendo.

Whitepaper says:

Like Bitcoin, all work must be done prior-to payout and nothing should be paid
speculatively on the promise to do work in the future.

On forum, BunkerChain Labs describe what could be a better aproach.

The post was very poor quality and didn't meet any criteria as far as content goes. It literally just was a call to give you money on a promise.
If you put some kind of effort into actually making a case that detailed how that advertising would be done.. show the prepared campaigns that are ready to go with screenshots.. and what the end goal might be, then it would have been more compelling to support.
I think a little more effort would have yielded better results.
