No, they have nothing to do with roleplaying. They're automated programs and/or real people who make accounts to promote their completely 100% unrelated services/advertisements. It's rather common for any type of forum to be targeted by spam bots, even abandoned relics like old proboards, phpbb, etc. etc. forums. As far as I'm aware the guild doesn't have any current preventive measures for them outside of just banning the account, though [@LegendBegins] can probably correct me if I'm wrong.

We [i]do[/i] have an autoban system, but bots have gotten craftier throughout the years and evade it. But it catches more than you'd expect.
