Conan Exiles is primarily a PvP game and therefore, like other open-world games, attracts the good, the bad, and all the others. Some servers will attract more aggressive players and giant reaping clans, some won’t.
If exploits are being used: Official Servers - Terms of conduct, guidelines and procedures
You can report, but since there are thousands of servers, policing Official servers is simply impractical. Exploits may get added to The List and get covered by Updates and Patches.
If bullying or spam building, then this is not exploitative, just rubbish playing. It’s unimaginative and can even simply be being done by disenfranchised players trying to make players give up the game, etc. (sometimes these things can even be ‘political’ of all things). You can try reporting via above link.
If no-one plays on a server and it is a ‘dead’ server (???) then you’re likely going to be safe playing on it. If it’s PvP, it is in the name so do not expect anyone else playing to play by the same rules.
You, and your clan, can move to another server that better suits you.
You can move to a private server someone else has set up as private servers are usually actively moderated and therefore harder to exploit/abuse.
You can get either do solo or with a group and set up your own private server where you set the rules.
There are a lot of solutions.
Funnily enough, if you have ever read Robert E. Howard’s books (available for almost nothing on That online ordering site) you will know that Hyboria is not a world of rainbows and unicorns, maidens and minstrels - and if any of those had made an appearance, they would have been over a pillaged and burning city, skinned, ravaged, and been crucified - all in that order.
Conan (and Valeria, Red Sonya and Thorgrim, et al) were not noble heroes and certainly lived by the maxim ‘what’s mine is mine - and what’s yours is mine too’.
Happily, the volume of toxic play is not as bad as it used to be. Many of the old exploits are gone (thank you Funcom) and resulted in many disappointed exploiters moving on to those other two or three open world games instead.
My recommendation: go private server. They are more fun, often have mods, and are usually moderated. […and here endeth the dissertation of the day…]
