Doing business on the Internet, I find all sorts of devious and downright criminal activities going on. I try to help people sort out the good from the bad by posting on my Anti-Spam Website about various scams I find.
But some people are involved in an activity that, although it is strictly within the law, I find absolutely despicable. There are people out there who spend their time looking for website domain names that the owner has accidentally allowed to "expire" and they buy them as soon as they expire. Not because they want the domain themselves, but so they can say to the former owner, "I'll sell this domain back to you for $20,000."
Or, instead of buying domain names that have expired, they buy domain names that they know someone else will want. They don't want the domain name themselves; they just want to be able to charge someone an arm and a leg for the domain name that they want.
This activity is directly contrary to what Jesus instructed in the Sermon on the Mount.
If you want to know if an activity is something you should be involved in, ask yourself this question: Would I be happy if someone else did this to me?
Can't you just imagine how furious those domain snatchers would be if someone did the same thing to them? And that, right there, answers the question of should I be doing this?
No matter what you do, always put your activities up against the test of the Golden Rule.
