sockslist.netは安全ですか？

This site is safe and I like how it has a checking option so it can verify whether the proxy you're planning on connecting to actually works. Unfortunately, the checking option is often inaccurate. Also, there occasionally will be some proxies that are hosted by malicious servers, so you should always the test the proxies using the check option because it gives you the domain and geological information of the proxy. If you want unlimited servers that are automatically checked more frequently, then you need to register for an account that will allow you to access the private area, aka the pro area. The cost of having an account is 30 dollars a month, so you might be better off using other free proxy lists. If you are planning on using Sockslist's sister site, *****, it is literally the exact same site except for the fact that Sockslist uses the SOCKS protocol, and proxyhttp.net uses the HTTP and HTTPS protocols. Also, Proxyhttp.net's private area only costs 20 dollars a month compared to Sockslist's price of 30 dollars a month. Overall, this site is rather underwhelming and so is its sister site!
