Let's take this one at a time:
You further waive any exclusive use of any content posted to the
Website by You.
- you surrender your exclusivity means that you're no longer the only person who can benefit from this content. The website also gains the right to use this content.
Materials or ideas You submit on the Website or to the Website
administrator or any employee, officer or agent of WebAnswers, will
not be considered confidential.
- The website will not be required to keep these materials confidential - they can be made public, on their website or other materials they produce.
May be used by WebAnswers, in its sole discretion, without any
obligation to compensate You for its use and without any obligation to
return any such materials.
- WebAnswers CAN use all your materials, as they wish. This means they can publish, modify and remix all your content at their discretion. Furthermore, if this content is used for marketing and business purposes, the website is not required to provide a share for you or license author rights from you. You are not entitled to any profit the website generates from these materials. You are also not entitled to moderate this content after publishing. You cannot request your content back or return any authorship rights after you submit the materials to the website.
Great, so far, all of these terms regulate how the website can use all the content that you have submitted to them or any party related to them. While you can't claim the content back, there is NOTHING here that says that you CAN'T use this content for your own purposes.
If nothing tells you using the content is forbidden, then, it is probably not forbidden. I'm not a lawyer. There are things that I'm missing, like an implied condition that I don't know of.
HOWEVER, I'm a content writer and an SEO, I'll tell you some simple truths:
- The likelihood of a dead business to sue you over submitted answers
in their platform is low.
- The fact that their terms and conditions
sets NO rules that forbid you to use the content means their legal
claim is weak at best. (Not a lawyer - double check.)
- At worst you will receive a "Cease and decist" letter, that tells you they are the rightful owner, and you have to stop using this content and take it off the Internet ASAP, and if you don't they will sue you. Which they probably wont, but they can..
I assume that you want to use this content to republish on the Internet, in which case:
Google does not favour duplicate content.
If this content is already indexed in Google (and the other seach engines) at WebAnswers, you will gain nothing in republishing it to a new website / platform.
The safe way to reuse content across other websites is to paraphrase, add more to the topic and remix with other information to create a unique peace of content. The topic is the same, the quality of the information is increased, and the content is uniquely introduced to search engines.
Use this information as you best decide, but the bottom line is, there are ways to do it smart and avoid any IP disputes.
I have used and continue to use and reuse content that I've previously written, and created for other websites, or submitted to online platforms. I have received one complaint from 150+ articles published around the web and 200+ published on specific websites. It was about an image of The Guardian that I have no rights to use in my post.
Most content writers just Google for an hour before writing a new article and surprise, surprise, the final product is just the same as the other 9 results on page one.
It's how it works these days.
