Do you mean shameless and irritating to yourself in the sense that you felt forced to resort to techniques that laid aside technical merit and honest discussion with your target? Or are you refering to devious methods to appear shameless and irritating to your market, that result in lots of sales?
I mean making lots of repeated phone calls, and I mean rule #1 of selling: ask for the sale. Pro sales people are always trying to transition from their current state to the end state; they do it by brute force at every state in the machine, and often construct entire new subgraphs of the sales state machine so there are multiple transitions towards closing at every state. Pro sales people are also really good at qualifying opportunities and don't waste a lot of energy on weak prospects.
All of these behaviors are extremely aggravating (even moreso if you're a bystander watching it happen):
* They're always bugging people
* They're always asking for progress towards closing
* They evince no actual caring for the customer's problems (that's the SE's job!)
* They won't give the time of day to someone they've deemed unlikely to help them close a deal
Think of them like Hollywood agents, like Ari Gold from Entourage, and you're not too far off. Except Ari actually cares about Vinnie Chase.
