Wikipedia defines domain tasting as the practice of a domain name registrant using the five-day "grace period" (the Add Grace Period or AGP) at the beginning of the registration of an ICANN-regulated second-level domain to test the marketability of the domain. During this period, a cost-benefit analysis is conducted by the registrant on the viability of deriving income from advertisements placed on the domain's website. Furthermore, users that registered the web site would monitor the sites traffic, click-through activity, and keep the web sites that were popular. People were also returning sites under the grace period which was known as “Add Grace Period” (AGP) that were even popular and just reregistering to avoid paying the cost of registering a domain(ICANN, 2009).
Domain tasting had a negative impact on the domain market by eroding consumer confidence in the system. Those who wanted to register names that were tasted and then let go, or those that saw their trademarks usurped during a tasting campaign… all were adversely impacted by domain tasting. The activities were also populating the internet with many useless sites. Sites full of advertisements, and useless information. These practices also had other negative effects for Internet users. Increasingly, domain registrants are serving malware to visitors who accidently visit their domains or sent there by spam, DNS poisoning, or other tactic. Malware comes in many forms, but typically, it steals personal information and money from the visitor. By remotely directing, malware can turn a person’s computer in a bot, or worse. ICANN community stakeholders became increasingly concerned about domain tasting, which is the practice of using the add grace period (AGP) to register domain names in bulk in order to test their profitability. On 17 April 2008, the GNSO Council approved, by a Supermajority vote, a motion to prohibit any gTLD operator that has implemented an AGP from offering a refund for any domain name
