Hey, I did a bit of research on this guy.
Here's a chronological account of what led this guy to rage-quit reddit and caused his subreddit to be banned.

*I use a ton of screenshots in this. Here's a link to the image album but IMO the text I'm going to put down below provides some much needed context.

Before we speculate on whether or not this guy is a spammer, let's take a look at his submission history.

To add to this, he never participated on r\Darksouls. He used it solely to promote his mod and he did so quite a bit.

Not everyone was a fan of this shameless self-promotion and this is how he responded to that criticism

Eventually this became too much for u\AnatharMerol so he called it quits.

Apparently not though, just 2 days later he submitted again to r\Darksouls and received an automated shadowban.

Once unbanned, he had a little back and forth with the r\darksouls mods

*Now comes this very thread you're reading this comment in. ITT he claimed that he didn't post on any subs outside of his own r\DarkSoulsBossArenaMod... That's not the case. He did 2 shadowban checks, first 3 hours after posting on r\darksouls and his second 10 minutes after posting on r\games

Now, he calls it quits again

This is /u/AnatharMerol's final post

After this he deletes most of his thread and his account

I go to r\DarkSoulsBossArenaMod and let them know that he, the sole mod of that sub is gone. Then this guy, u\FatherofDeath shows up and blames me for u\AnatharMerol account deletion.

There's no way to prove it but I think it's very clear FatherofDeath is AnatharMerol. New account just after AnatharMerol's account deletion to respond to me, same exact writing style and spelling mistakes.

Here's thread made by him

Here's the mod's Facebook page where he blames me and calls me names.

r\DarkSoulsBossArenaMod gets banned

For posterity, here's a screenshot of /r/darksouls mods pre-deletion
