This is a truly good practice. Coming from SEO forums, i'm surprised how it's accustomed here and on other domain forums to post plain domain names. It's always good to post them as images of to obfuscate somehow, like " domain\.com " or " domain (*) com " for example. Why? To not let Google record the fact of this domain being on sale. The reason is simple: when someone buys a domain for his real business or website, the last thing he wants is to find later that this domain was once on sale on some SEO or domainers forum. So my attitude is : we should respect our buyers and defend their interests. I never post domain names in a plain form.
