So, four months "invested" in these flat earth forums now, and it wasn't a waste of time, but an interesting experience.
My investment was lost, but, like in trading, I learned lessons from it.
The first lesson is about forums in general.
It is easy to create a forum, and it is easy (with hard work) to get a few dozen people to join it in its first month.
Then something interesting happens. You run out of friends and contacts to join that forum, and, naturally, as time goes by, the existing ones lose their initial enthusiasm and stop posting.
In most these flat earth forums I've seen, out of the roughly 50 registered members, only half ever post.
Then as the weeks go by, about 2 per week stop posting, so you're left with 15 active members after one month.
If one of the most active members leaves, then the forum is totally deserted after just another month.
It doesn't take much to offend them and make them leave.
Especially on these flat earth forums, where almost every single member, including me, is not leading a healthy lifestyle. And this almost always guarantees mental imbalance and lack of objectivity.
The most common problems on these forum are:
1) the administrator is intolerant with people who disagree with him, and he bans them.
2) the members are intolerant with people who disagree with them, and they insult them.
So, this produces the result that these forums become very quickly deserted, because of these consequences:
1) people get banned and the forum loses members
2) insulted people leave
3) insulted people respond to insults, and cause the other person to leave the forum
4) people, afraid of being banned, stop writing as freely as they otherwise would. And less posts leads to less participation, and less participation leads to fewer new members... in a vicious circle that makes the forum become deserted, as few people like to write things by themselves. I like to write here all alone, but because i have readers. Otherwise I would not like it, and would stop writing.
Another thing that is common among flat earthers is that they are mostly frustrated and angry. Maybe not angry at you, but at someone. Usually the Jews. So, if you defend the Jews, like I did, you're going to have problems.
The majority of them are historical revisionists.
The best lesson from these forums was... to avoid them.
I could still read them, but I will stop participating in them.
They cause a lost list of problems, but the main one, which is the summary of all problems, is that you end up sleeping less because of them.
Having said this, despite not sharing their bad manners and anger, I still share most of their conclusions about the world and its history:
1) the earth is probably flat
2) 911 was an inside job
3) JFK was killed by the Illuminati
4) the Illuminati are a satanic elite, that engages in blood sacrifices
5) the moon landing was faked
6) lately the false flag attacks have increasingly become hoaxes, such as: Boston Marathon Bombing, Sandy Hook, Charlie Hebdo.
