In my experience many of these properties end up going to tax auction not because the people don't have the money to pay the taxes, the taxes on vacant land are usually minimal, but because in most cases people have forgotten about them, inherited them, or otherwise don't have use for them. You deciding to buy the property or not buy the property is not going to change the fact that someone is going to lose their property, besides if you don't end up buying, there is someone else out there that will. The best deals in real estate aren't always the prettiest ones. Investing in Real Estate a lot of time deals with seller's who are going through tough times whether it be having a property foreclosed on for financial issues, needing money for medical problems, or inheriting a property after a death in the family. Land is hard to sell so in many of these cases you may be helping someone out by getting them money for something they desperately need in exchange for something they may not have any use for.
