If you have the skills, utilise it for constructive things.It is sometimes seen that technical persons having IT skills utilise it for destructive or wrong purposes rather than utilising it for constructive, useful and helpful things.
IT persons with hacking skills use it mostly for wrong purposes. Such IT persons hack the entire server and insert malicious codes thereby destroying the reputation and worth of some good websites. Some hack it to divert the traffic to some malicious ads and earn on efforts of others and many hack it to extort money straightaway.
By doing such activities, they not only waste valuable resources and time but also the effort of so many man hours that has been put to establish a site and maintain it. Still the IT sector has not matured enough to be able to identify and catch the culprit, there are enough loopholes and these are misutilized by few who have the detailed skills.
Wouldn't it be better to channelized such skill and talent for welfare of general masses rather than just utilising it to satisfy ones' own greed.
