most people answered in detail, but I see one key difference being missed. Whatever use you have, mobile proxy is the one which can never be 100% detected or 100% banned. Unlike residential or datacenter. Because mobile proxies are used by mobile carriers and they use CGNAT technology which simply means 50-150 users share same IP. So say you are spamming tiktok or instagram. Your accounts will blend in with real people who are on their phones actually using it normally. And IG/TikTok can't ban that ip or blacklist it, since it will be churned through an entire country which is how european mobile carriers work. Each time a proxy is rotated, you will get assigned a new IP from the entire country geo wise. So basically you are entirely undetectable. Unless you go crazy and spam 30+ accounts on the same thing, then the service may flag the IP as more risky and get you rekt more frequently. But mobile IPs will never get banned due to this reason. Residential and datacenter if spammed too much will get flagged eventually and the flag will stay forever, since they are fixed (not forever forever, but you know what I mean)
