Yahoo! PPC just cracked on me, any advice?

Whats up fellow BH's

I been using Yahoo's $100 promo codes for almost 2 years now, and it seems like just a few months ago every time i was signed up, they wouldn't apply the $100 credit unless I hounded them via email. I'm wondering if any of you guys that use yahoo ppc are experiencing the same thing....an example of a most recent active $100 promo code i used was US2375, in which they never applied the credit and after immediately hounding them, they threatened legal action for signing up new accounts with new or the same promo codes. Bottom line is I don't care about their threats I'm just wondering if anyone currently uses their promo codes and has the credit applied upon signing up.... Advise would be greatly appreciated, Thanks!

I would assume you're using proxies and VCC's to signup and use these accounts thru? I'm sure they would catch on if you're using the same thing over and over lol. But no no problems here.

I use this link and it works great. I've never had a problem getting credited within 3 days.
