How many to stop typosquatting? 🤔
The Internet grows, you'll always be one short.
1. The number of TLDs is evergrowing;
2. There are many potential typos to exploit;
3. Unicode 2nd level domains allow for countless tricks;
4. Too many domains with the same content can harm SEO.
The best solution is to keep a good relationship with all search engines.
SEO is your friend, as most netizens lazily click on the top-most search results.
