nice list seobunny :)
find that a lot of people overlook this far too easy,not every bot is your friend
i scrutinize every bot that lands on my sites

The worst of them probably pay no attention to the robots.txt file. It is completely optional for the spiders, not an iron gate. You will cut some bandwidth use by using the robots.txt file, though.

me personally i ban them via ip range from my server as its easier for me as i have around 30 or so sites running there

ooppZzz, I didn't know about these bots before. Knew only some bots like google bots,yahoo bots,baidu bots and etc !! and I didn't block any of them

After reading this useful post, i have checked bots status visiting my blog today through StatPress plugin and i am surprised that today 106 spiders and 16 feed agents have visited my blog. Previously i always ignore them but now i need advice that Why should i disallow these bots? Seobunny has provided a good list and i think i will prefer to use that list rather segregating my own.

yea, I also want to know the same, why should we block these bots from coming to our sites ? what are the advantages if we do so ?

Some of those bots are content or email address scrapers. Those you definitely don't need. Others are providing you with copious supplies of comment spam, unless you are following parada's techniques you probably don't really need them, either. Yet others are registeration bots for various CMSs, or content delivery bots where applicable. They all add some load to your server and take some bandwidth.

best thing i can advise is research each bot you see crawling your site and decide for yourself if you want to block it
i could post a list here that would take you half an hour to read
if you have a wordpress site install "Visitor Maps and Who's Online" plugin
this will make it so easy from the admin side of wordpress to get a list of bots just change the setting at the top to include bots
Visitor Maps and Who's Online - Wordpress Plugin PHP Script - Long Beach Weather
rain222
it can stop content scrapers taking your content or feeding from your rss,it can save bandwidth,stop your emails being harvested,stop bots who ignore your requests to have certain pages indexed,stop spammers and so on
maybe a dedicated thread to bad bots would be a good idea

yea, it would be nice if some one who know about this subject can start a new thread to tell us what kinda bots are bad to blogs and sites
