Your IP is public information. You can make it difficult to find but realistically it doesn't take much to rip someone's IP. I got DDoS'd last week for about 30 minutes because I called someone on GTA:O a cuck. stuff loving happens, living in fear of being DDoS'd, or your IP getting posted on the internet for that matter, is incredibly redundant.
Nobody is going to spend money on a botnet to DDoS Maxx to kick his dumb ass off the internet for approximately 5 minutes, unless he was doing something really stupid, like spamming a cytube for example.
