So for right now I would suggest disengaging Yes you were obviously there first and have made substantial edits to every article you ve listed and he s a recent newcomer However you don t WP OWN the articles and the fact that they form a pretty narrow topic is a reasonable defense against wikihounding accusationshe can simply say What I was just editing a bunch of RC articles how was I to know this guy was already editing all of them and have some plausible deniability So disengage don t escalate and use the dispute resolution process WP 3O is a good start between two editors to demonstrate your good faith interest in the articles Oh and ask for more help if anything else starts going sideways Cheers
