Bots. i would call a bot any program that helps u use gaia. Some bots are ok but most get u band if some one reports u.
The thing is if u use them it could be bad and this is a few things to Look out for.
if a bot or program tell u it can make u gold then it can't be real and if u use it gaia will ban u. Gaia never makes programs to get u gold or items. they have grant links for free items and games for gold stuff u will fined on gaiaonline.com
if the download is not gaia it is fake and if it was real u would see stuff about it on gaia and i bet it would not be free. it would be all over gaia if some thing Like that came out and gaia has no off site items or gold.
Bots for towns might Look Like addons but it is a progam made by a hacker and the guy that made the program might get your password even if it tells u they don't log passwords or even if it has no pLace for a password. it can still hack your pc and track what u did on gaia so there is still a chanse u could loos your account.
Only good bot might be a tool-bar but i would search in forums on gaia B4 useing it to see if any one els tryed it.
