when I answering a question with my website url . the yahoo answers answer not showing up. but after I remove my url, the answer is showing again.. is there anyway to bypass this url filter .. I already have Level 2 account...

shrink it using bitly or one of the many other shrinkers?

tried both bitly and tinyurl . but still cant bypass it ...

but I can post urls on other categories..

1) Buy a "throwaway" domain or use one you already have and don't care about.
2) install automatic forwarding script on that domain. Point to your money site using the script.

So instead of posting a yahoo answer link to hxxp:// moneysite dot com
point to hxxp:// throwawayDomain dot com

When user on Yahoo answers clicks your link, the script autoforwards to your money site.

If link is banned by Yahoo, change to anther throwaway domain.

Use VPN/proxies when posting Yahoo Answers. Use mutliple Yahoo accounts.

That throwaway-domain system works. But YA also hides answers that contain domains that have never been posted on there before, it's not just that they ban a domain after being posted x times. I think, it depends on a bunch of more factors. However, it's frustrating.
