There are some problems as garena has started to appoint admins or such, to finally address the problem and reduce and trim the bot overcrowd. As you might notice, Russia RPG room 01 and Russia TD room 01 have [no hostbots] in front of their names.
As of now, Russia RPG rooms have IP banned the farmbot previously so it never entered there to make games. Plus EU 01 also is void of bots except for LTD. Changes will come according to how this Garena decision goes.
Currently Albia dota 01 is our safe haven.
I'm fairly certain Garena can no longer play via lan. They removed the feature which was pretty dumb. As for people who actively play it, well... a lot of us (at least myself) are waiting for the new version. Of course there is always clan orpg @USWest on battle.net and a bot that hosts named gaiasdungeon but I don't think either are active at the moment until the new version is released.
