I've personally known a bounty manager who manages multiple projects creates a new account for each project that she manages (well, to be precise, Copper Member). But if the project is really weak/without any prospect, it's very likely the bounty will only waste hunters' time.
Sorry to say this, but I don't like this way of doing things and it raises a lot of flags.
The only reason I can think why she would do this would be to avoid eventual repercussions on her account if the project turns out to be a scam, fail or anything wrong goes with it.
Any other explanation of why she might be doing this? Cause I really can't think of any legit one?

You can easily remove the "newbie" from the text.
You shouldn't do any of those even if the user is a hero member or legendary with only a bit of green trust. And even in those cases, if the sum is something that would hurt you finally and not pizza money, then DON'T!
