Discovering the domain you've just purchased is going to bring a lawsuit to your door is BAD.
But finding out you're the scourge of the internet takes the first two scenarios from, "oops, I messed up" to, "omg, I'm screwed."
That's right, I'm talking a spammy, scammy, bad quality domains with TONS of backlinks that tell the world your newly acquired domain is not reputable, safe or legit.
Basically, it's like you just purchased a drug dealer's house on the bad end of town, only you didn't know it. Now you've tried to start up a sweet shop but you've got nice families walking quickly past your house while covering their kid's eyes and making sure they avoid your home at all costs as the internet all but says you're the worst of the worst. And those results don't go away. EVER.
If it's on the internet, it stays on the internet.
And they don't diminish from search results for at least a year if not longer. It's going to be a losing battle. You might as well cut your losses, try and unload that bad location and start over.
Wow. That's bad... I'm so sorry.
So how can you make sure you don't stumble into any of these scenarios?
First and foremost, run a DBA search and make sure your name is unique and not being used by others. Because that is not going to work out well for you otherwise.
Run a search on Google, Bing and even Alexa - make sure the results you see are positive and not recommendations to avoid the domain at all costs. If you see another business using the name, STOP! Start over with another name idea. Don't pick a business name that is already in use by another business. Not just for the legal reasons but because you will struggle with search engine results. Nobody has time for that.
Search social media accounts to see if the handle you want is available on every platform. But don't grab them yet, you're still researching.
After you've researched the domain name you want and are certain there are no negative spammy, scammy or trademark issues (don't forget the story about that Mom who made cute little cloth diapers) - then you can purchase.
Finally, go back and secure all social media links and online accounts you intend to use that are associated with your business name. Don't assume it will still be there in a week, or even a day. Do it the moment you decide on a name.
Lastly, create your business cards and other promotional and marketing material.
I've been programming, designing, writing and publishing professionally online since 1995. I've worn many hats throughout my life, but the common core of my career has always been media. Besides theportfolio you see on TNW Creations, my internet presence has been substantial for over 2 decades. In 1995, while still in college, I founded TNW Creations and became part of the grassroots development for teaching the Lakhota language online. By 2004, my bilingual work was listed on many sites, including National Geographic , Encarta and Touchstone Pictures Hidalgo. When I'm not developing and writing, you'll find me managing MagicStoryLand.Com, creating kid-friendly game & video content, investigating and initating hostile website takedowns, posting salty articles about cyber threats, moderating UnifyLife.Org and enjoying my community, church & family.
