I don't see a list being updated anywhere so I thought I'd make one with all the recent bot closures. These are from my recent explorations and I may have missed a couple so let me know if I should add any.
List of bots as of 1/10/12-
Paid bots:
Honorbuddy/Gatherbuddy-
Seems to be the only big reliable bot still being supported. They seem steady, but who knows what may happen with the ongoing lawsuit. The only bot with emphasis on PvP. If money is not an issue this is a good choice.
WOW Bots Gatherbuddy & Honorbuddy
Pirox/PvPtool-
All operations ending 1/25/12. No new registrations being accepted.
There was a thread with a "cracked" version that looks like it got deleted.
Pocketgnome-
Mac only bot. Like Honorbuddy, they are currently fighting a big lawsuit with Blizzard. It's going both ways, Blizzard sued them in december AFTER they had already sued Blizzard a month before! They released a statement saying they will not stop selling their product until a court orders them not to.
Pocket Gnome - Bot for Mac for a popular MMO
RwBot-
Still going! Pirox profile based bot. Seems to be a solid bot after hearing other peoples reviews.

Free bots:
Lazybot-
Shutdown as of now with no official support. This was one of the most used and reliable free bots. Here is an UNOFFICIAl download link that I did not upload. Credits to Zim804.
MEGAUPLOAD - The leading online storage and file delivery service
For profiles google or WoW Bot Maps And Profiles
Cybot-
Still working! A little rough around the edges but has a lot of potential as the only free bot being still being developed that I know of. There aren't really any questing profiles (all grinding) and a couple of the bg profiles could use improving, but the gather profiles work great. Profiles seem fairly easy to make
