I don't waste my time with online psychological testing - without contextual interviews or reliability scaling, psych testing is absolutely worthless, and online versions even more so because they tend to use binary response options. Reliability scaling is particularly important - without it, anyone with a little psych education could manipulate the results to make them meaningless.
Personality disorders do have legitimate criteria defined in the DSM that go well beyond simple statements like "people are different" (to be diagnosed with a PD it has to have a significant impact on a person's lifestyle, for one), but the fact that these tests have identified high and very high traits in a number of people here make them too all-encompassing. The occurrence of most PDs ranges somewhere between 0.5-2% of the general population, with slight variances by gender.
So yeah, not bothering - it's a waste of time.
