Single post in Implementing A 'Block' Feature

As someone who is new to this site and genraly polite I feel a blocking feature may not be the right answer. If someone is annoying one for whatever reason you should first ask them to leave you alone and besides if someone is breaking site rules or being rude I am pretty sure the moderators on the site could do the job. A blocking feature would just escalate the problem and cause hurt feelings. So with that said I am against a blocking feature.
