Technically it is not Spam but it is an inappropriate thing to ask, esp from one seller to another. So while Spam is technically not the right term, it is close enough.
@ahsan457 FREE work. How about I come and take some money from your bank account? Will you let me do that?
I bet you say no (or give a smarty pants response to try to distract). Taking without giving is not cool. Me asking to take money from your bank account is the same as me asking you to give me some of your (apparently) valuable time, just because I feel like it. It is inappropriate.
So, please don’t do the come on man thing. You did the wrong thing. You complained like the other seller - the one you insulted - did the wrong thing. You are in fact digging a deeper hole for yourself, advertising to all the other quality sellers here that you are not a class act.
Your call but if you don’t want to be called a poor operator, don’t be one.
