You are asking for a large sum of money WITHOUT collateral which is one of the lending section rules. You should be getting negged based on that.
Don't see how Quickseller overreacted.
Collateral is a
Suggestion not a
Rule...I lend without it from time to time. It is the lenders choice if they require collateral to lend or not.
The rule of "No Collateral, No Loan" means that in order to get a loan you must give collateral that is equal, or preferably higher to the amount you are being loaned.
If you completely ignore this sticky and make a loan request with no collateral, without having massive trust on the forum, the chances of you getting negative trusted feedback and therefore having a Trade with Extreme Caution tag is almost 100%.
Seems more like a rule than a suggestion.
