Why do my answers not show up on the Question link?

That's because you are using Yahoo Answers to promote a website on here.

Looking at your answers then you have not used this account for years and then come back and start answering questions from another account which hasn't been used for years apart from to spam the same link recently. You may call this "testing" but you are asking with one account, answering with another and spamming Y!A. I would strongly urge to you quit asap as you are jepodising both accounts by doing that.

You may not realise but this is something which other users like (spam) and it is not permitted. You can include the link to your website on your "About Me" of your profile but you are not allowed to answer and include it on all of your answers.

In the past it would result in the suspension of your account (and this can happen still nowadays as well). Instead Yahoo hide the answers from view so unless the spammer checks (and to be honest legit users don't check if their answers can be seen logged out or with another account) then he/she won't realise.

I appreciate you may think it's harmless, but please do appreciate that legit users of this site really don't like spam and don't want to see it all over the place and that's why it is reported or hidden from view.

There is nothing you can do to make them appear again. The best thing you can do is to find another site if making money for personal gain is your aim. Yes there are some answers that slip through the filters and are shown but invariably those accounts will wind up being suspended eventually as well.

Yes you did exactly that 7 years ago, (including giving your accounts Best Answers each way between the two accounts) but times have changed and Yahoo Answers is not here for your personal gain.
