Yeah, not a lot of pictures for this one.
Okay, I don't comment on forums. Mainly because the two major ones: ranger crew and ranger board, are associated with power rangers, something I don't want to be associated with, and I'm busy enough as it is. I still read forums for news, updates, links to subs (I found out about one of the major sites I use to get subs thanks to these forums), and the occasional larf (that's laugh in britspeak).
After looking through the three big forums: rangercrew, rangerboard, and henshinjustice unlimited, I was able to find out different patterns of posting or posts themselves that pissed users off, and somehow pissed me off as well. Most of the perpetrators are newbies, but those who are still a little green or regular users shouldn't be making these mistakes. Usually they will be corrected by a moderator or a veteran, however, sometimes moderators don't have to correct them (and they have every right not to, moderators are busy people to). Either a bunch of other users will vehemently correct them. If the user doesn't learn from their mistakes, it will become kind of their signature, like you can tell who is making the comment even if they changed their name, or a forum war will erupt--and although these are hilarious, they are still somewhat useless and annoying for people who use the forum or just read it.
So here is a list on how to piss people off, specifically on tokusatsu forums.
Do not adhere to the basic rules. This includes formatting, quotes, signatures, spoilers, all that good stuff, which usually requires some html. This goes for any forum. Now, a lot of readers aren't annoyed by this, but the more meticulous users are.
Start a fandom war. This goes for pr vs. sentai, pr vs. kamen rider, kamen rider vs. sentai, etc.
Start a shipping war, or dominate the ships. Now, I admit it, for Shinkenger I am a diehard Takeru Kotoha shipper. I was intimidated and discouraged while reading the forums after the support the Takeru Mako shipping got, and how people worshiped Mako. I talked to my fellow Takeru Kotoha shippers, and they said they don't even bother to look at the certain forums that are dominated by the opposite shipping. I'm not sure if they scared us or we just got sick of it. So don't be an instigator. You can write once in while about it, but you shouldn't make every other post raving about the ship, and saying stuff that isn't evident at all. Because you're bound to attract an shipper from the opposite side who is bound to be upset. And behold: shipping war. Also, a lot of these shippers are self-inserters. Therefore, if you blatently insult one ship, you are indirectly insulting the shipper who sees themselves in this kind of relationship, whether if it is a real life relationship with someone that is a lot like the character, an crush on someone who is like the character, or an admiration for the character or actor. So you make the shipper feel bad.
Start a political war. Back to shinkenger, I remember when some people were upset with how Mako wanted to be a housewife and a good mother. Some feminists were upset about that, and said that it's non-progressive. Some feminists who were realists, or realists who weren't feminists said, it's just a kid show, and then more conservative people felt insulted, because they were or knew people or were married to people who are homemakers. Then people actually started insulting the conservatives, and the conservatives insulted the feminists, and I swear I saw a few death threats. I myself am an equalist. I believe everyone has the right to choose what they want to do--even if they are a fictional character, but fictional characters have no free will and--whoa existentialism. But yeah, it can get that dirty.
Rite gramaticaly incorrect massages with speeling misteaks that sond like u r righting this wile u r drunk. This usually invokes the wrath of grammar facsists. And you don't want that.
Discuss something that isn't in the forum topic.
Although this doesn't count as a fan war, just make one offhanded comment on how, for example, pr samurai is better than gokaiger in a gokaiger topic forum. This isn't fanwar bait, but it does make a lot of people frustrated that someone is on their turf: a forum specifically for their interest.
Attempt to act as moderator or dominate the forum. Forums have moderators. Don't try to steal their job and then claim you are the original one, or are better than them.
Repeatedly ask, "when is the sub coming out?" "when is the episode going to be on the internet?" "who uploads the movies to the internet? Or even worse "when is the episode going to air?" or "when is the movie coming out?" Subs take either a short time or a long time to make depending on the language strength of the subbers. Instead of asking, go to the sources themselves to see when the sub is coming out. Who knows, they might have released it already. Also, usually a nice poster will just post a friendly link without being asked to to a stream or episode. You know when the episode is going to air, and when the movie's coming out. Google it. Finally, it's not a good idea to repeatedly ask which specific person uploads episodes or movie (especially youtube). Why? Because Toei has been purging copywritten videos from youtube, causing people to create several accounts, and make unlisted videos. People's accounts are being disabled because of it. If enough word is spread around, the people who are doing purging might catch wind of it, and it will be hard to find sentai on the internet. These uploaders like to be secretive.
Ask the above questions after being answered or corrected. You got a response, an answer, or you upset a bunch of people who told you to stop. So stop.
