Not a single web site should go online without proper maintenance plan.
If you'r website software is not maintained it's vulnerable for hacking or possible loss of performance.
Software vulnerabilities are the main reason leading to the hacked web sites. Fixing the hack is pricy compared to the security maintenance not to mention the lost reputation, stolen data etc.
