OnlineGuardian freezing member activity?

Hello, some of my members have received account freezes as time has gone by. To unfreeze their account, they must go to OnlineGuardian website and type in captcha. This has been because they "detected suspicious activity connected to [user's] account". I believe these members have done nothing wrong. No copyright infringment, hate language, fraud, etc that it says they have done. In fact, a lot kinder than even moderators around most forumotion sites.

What I am asking and wondering is:
1) Is there a way to turn this off?
2) How to contact representative?
3) How does OG identify bad user?

Why I ask #3 is because these two users who had this happen are similar in these ways:
1) They both use common proxy.
2) My forum is for writing stories, and both wrote roles of a vicious and hateful character before their freezes respectively.

So I am wondering why OG has done this. Is it because user on other website using same proxy have done bad and is frozen universally? Or that OG is carried out by bots and not humans and so have misunderstood the activity? If it is first, that is an issue.

If it is second, that is a bigger issue. Though all members are friendly to one another (or banned for misconduct), in the forums Person A might say "Character A looks at Character B distainfully and says, "You? You're pathetic, useless, etc etc" and others would react, saying "Character M turns to Character A and says, "Stop being so terrible!" and meanwhile Person B makes their character sob and break down, while in actuality everyone is enjoying the plot twist. That is a simple example, but this is integral to good stories that the members try to create.

Answers to all of my questions are greatly appreciated, thank you.

1. No
2. No
Reason is that this is software that was created by Forumotion to prevent unwanted content and to prevent harmful activities.
3. It says what is does on the site. "The service Onlineguardian aims to develop software and hardware solutions to prevent any host with the presence of illegal content on web communities.

Our systems detect behaviour or content which could adversely affect the hosts and the Internet, such as hate speech, child pornography, bank fraud, any form of copyright infringment…

Onlineguardian, in agreement with the web hosts communities affiliated to its network, reserves the right to take necessary measures in case of violation of the site hosts terms of services."

Seriously? That sucks then. So is there no way to stop this from happening? If it is a software that picks up words alone, then this means my forum is screwed.

By #3, I meant does it identify by IP address?

Also, what is necessary measures? Will accounts become deleted for doing nothing?


EDIT:
Sorry if this is detection software, there must be some sort of way to manually remove the detection and/or software? It would be bad if forum members kept being banned. Actually, that could even be a make or break to move so that members won't lost their accounts. If it's scanning globally across forumotion, maybe my forum could be added to a "no scan" list, even though this is asking a lot?

I cannot say since I don't have any information on this and my guess is that they don't want to say a whole lot on this.

This cannot be removed, this is to protect their software and other users.

Hi,

All the information that has been revealed about this software is that;
A email address that looks like a spammer, or a user that posts quite alot, within a short period of time, or the use of using the same text often in a period of time, ie, copy/pasting an article from say, the local newspaper into a thread, x amount of times, or creating a new thread with that article x times.

The x denotes a time, but that hasn't been given as yet, and unlikely will ever be.
I'm sorry but there is no 'do not check' list, and highly doubt there ever will be as this is for the protection of your forum.

Okay, thank you very much, but I know FOR SURE these members who are being frozen fit into none of those two categories. If IP address is taken into it like Codyy said (or use of "rude language" even if it's part of a story), I guess I could understand. But since it apparently isn't, that just annoys me even more. -.- Okay then, I will either learn to deal with it or move, which is sounding like a better and better solution with all these great (no hosting obviously) phpbb providers out there.
Solved, locked.
