okay... title was a click bait.. :P
sorry...
anyway...
Last night... I created a camp on exoclick and I got this rejection note:

so today... I copied the campaign... did the opposite of the rejection note... but it got rejected again and this is the note says:

so which one is it?
u fucker :P

nice headline, high CTR!! haha
Lol their staff/system can be a pain in the ass sometimes.
With relation though to that specifically though:
Daily Budget is too low for this type of Campaign please review- e.g. If you are targeting 150 million impressions on a budget of 20 EUR/US you will most likely exceed this (servers take a few minutes to stop such high volume traffic).
We want to alert you to this possibility so you can adjust the campaign settings to something more realistic. NOTE we generally only warn you once so as not to delay future campaign approvals
Bid/Capping/Daily Budget is too high please review- Excessively high bids or incompatible budgets are not permitted
Cheap shot! Got me to click though.
haha :d, I was hoping it was my account manager there ha
Holy post bait, was expecting some crazy flaw! Faillll
They do this to prevent campaigns overspending since their algo never pulls out in time 
Fyi - in copywriting it's time tested over and over again --
"SEX -- and then tiny... "now that I have your attention, let me offer you wash machines of brand XY" -- it does not work.
And on forum like this it only makes it less organized.
Ontopic: what is your question -- isn't it logical -- bid in between those two extremes.
I got it sorted out by @buttonedup post above..
:P
sorry for the trouble..
