One thing that could be tried to slow down botters, would be if there is a dangerous creature (say 300 HP, 1000 dmg, but non aggro) creature in the spawns where it's a suspected botter. That mob wouldn't attack anyone except if you aggro it by hitting it or trying to sweat it.
it could look like the normal creatures, but be a "mutated" version. It could either be permanently spawned, spawned in intervals or spawned manyally by, for instance, planet partner or MA.
That'd be easy to explain to all the newcomers,
"Don't attack that mob, it is only spawned because we have problems with bots in game"
Or what happens if you attack it and you ain't a bot? (if its perma spawned)
People are curious in this game, if a mob looks different - they will try to take it down... If I were a beginner and had a gun dealing 30 damage, I notice that 10%ish of the hp falls off the mob in one hit I'll keep hitting it, until it reaches me and then it hits me for a HUGE amount of damage... So I go back... Will the loot be just as normal then? So all of a sudden regular players - mostly newcomers - will have those mobs as a bad experience unless they were taught what it is.
I mean.. having additional mobs spawn to stop botters ain't the way to go I think...
Better make it easier to report some one for it, and a much quicker response from MA and actual actions taken against the avatar, get some volunteers to help MA, like the guides you see around calypso, that can TP to said location when some one reports another for botting by right clicking on the avatar -> report.
have them come investigate, it is quite easy... if they do nothing but auto move to target and auto shoot, dont walk in any other fashion, doesn't communicate - investigate further.. certain patterns must be used by those using bots.. like we have seen all over youtube ... fly a vehicle in front of them, or stand in front of them.. they don't react, but the avatar simply keeps moving to target. If some one blocked you, or some one landed a quad between you and your mob - what would your reaction be?
I would certainly communicate and ask what in the F are you doing?
These "bots" ain't sofisticated.. It is just macros on keyboards set to repeat, or a simple .bat file that runs commands over and over again in the top window.. Some bots even fail to loot and just run around shooting then don't even loot because they messed up their own script...
Don't add additional mobs, that will only frustrate new players and add a "WTF" reaction to those encountering the mob..
