If it is what you think you should do, then I guess your conscience sees nothing wrong with it, and you won't find yourself regretting the behaviour later.
I agree with you 100% about her banning methods. I don't like being uncomfortable with the idea of being banned because it is very hard on someone's reputation and I can see how it can make a difference with someone in control of a situation because of that. I would feel the same way if it were me who had her abuse me. I guess I was lucky that she blocked me before I even tried to sign in to post. SMH If she had let me in, and banned me, and I did not feel the way I do about not doing harm to anyone in any way, the solution to foil the abuser so they are hard up for anyone to abuse, isn't it? BTW, you will never be alone if I am here because I will help you deal with her any way I am able to, ok. What she does is an abomination, did you know that? I looked it up to know what I can use it for other than abomination and it's basically disgusting. So what she did was an abomination. (Fun eh?) It's a lot of fun to stick that in when they are protesting something that isn't true according to the scriptures. Telling them randomly "What you are doing is an abomination."
is easy to throw them off because it isn't necessarily only about sin. And they like to throw that word around because it was used by Jesus, but they don't understand that it was to teach us what sinning was by pointing out some to us. He did the same thing with the multitudes when he taught them in a way that they could understand what he was teaching them so they would not want to sin, and would want to follow him. Those sins are no different than others, and if our sins are sins by any definition, they need to be repented by choice.
Is she the person who bans for a lot of sites, or just her own uhh channel?
The reason I ask is that I think your best way to make your point is (if you are able) to set up a channel called something like Checkmates Outcasts, or something. Anyone who has been banned in her personal channel will go there and so will people who are surfing the channels for things. Eventually, she will know about your channel and she will not be able to ban one person for what they say on the other channel. Let her have her channel, so you can attract more people and then she will not be able to ban a lot because there won't be a lot of people who will post there if the word is out in the community either. (This is ignoring the fact that there are many more people to look and completely agree with her and her minions). If people find out about her, there will be less people going there to be abused by her. Which is what you want, really, isn't it? You don't want to necessarily abuse her, you want others to be treated better by her, which is like a pipe-dream. Closing up her shop because of the numbers is better than upsetting her isn't it? If she is mentally ill, and I think she is from what you and others have said here, some of what you do is actually harming her mentally. You might be pushing her to an edge by doing anything to punish her, but rather you take away the people so she has no one to abuse.
I know it's my idea, but I think it will be more effective than down-voting her. Hopefully, if it isn't keeping people away from her site to end the abuse, it will be the fact that I expect that everyone who is trying to hurt her too, might go to 'your' site and leave her alone and heck who knows, maybe it will be an improvement to her mental health. Or maybe it will help others to encourage her to seek help. We don't have any way of knowing how it will affect her by doing this, but it will reduce the people who are abused by more than down-voting her posts, it will get people away, and get people to come to find out what it is, a board for people who have been banned by the Fundies, and hopefully more people will just stay away from the abuse in the first place.
What do you think about going for taking the abuser away by being more popular with the people she abuses and bans, so they will go to your channel to complain or whatever, and she can't do a thing about what the people are saying. In the meantime, if you discover any Fundies in your midst spying so to speak for 'Lady', it will not feel wrong to ban them because she bans others. Just try not to abuse them (the Fundies) too, or you will be no better than she is. Be wiser and do it from the other angle so it is going to do the same thing.
I'm trying to help you, Jocasta, because it is you that has to live with your decisions. If this ever comes back to you, and you end up regretting anything, you will have no way to change what you do. There is nothing to come back to you in regret if you take the situation in control, instead of letting her have control.
May God bless you with Peace and Joy in knowing that you can overcome evil with good And this is one of the ways.
People would likely appreciate a place to go to vent about how they felt when she was abusing them because everyone will feel the same way, right. I hope you like my idea, and that it will help you.
