This is not something we support. We would hate for our fellow players to get banned. So please DO NOT USE ANY CHEATS, HACKS, OR MODS with any Dark Souls titles.
The End User License Agreement (EULA) that all players must agree to follow before even being allowed to press "Start" to start a new game states that using such things will lead to restrictions/bans (regardless if they were used in Offline/Online mode).
Thank you for your understanding in this matter.
