I know I shouldn't be saying this but , IF....a thread is upsetting you....why would you keep going back to it?
The old saying Curiousity killed the cat....sort of rings true.
It's himan nature to do this, but, we are grown adults I'm expecting, so we should know better than to be tormented by a single thread. Sure I know a topic can get under your skin as many have mine.....and yes I am guilty of doing just this also....but......
I have found on some sites you can stop yourself from having access to specific sections of it. An example would be ADVRider. If I go onto the thumper, Canadian or their off topic sections....I'm easily sucked into thses BS threads where I can't stop getting sucked into. They have a way you can block those sections from your sight. That way I can still visit the sections of ADVRider that I want to visit without getting distracted. That site has by far the best travel and adventure sections that I have come across period for adventure riding. That i what I use the site for....nothing else. The rest of the site is full of trolls baiting people who don't fit into their little cliques or families and they take great enjoyment from upsetting you personally.
So, once again.....select the specific areas you want to see and visit and stick to them......don't open the off topic forums if you have some idea that there is a topic that will get you seeing red.
Plus the ignor feature is a good tool also. There are always some arseholes on every forum who troll and bait people as their way of having fun.....screw them and put them on ignor.....it helps......over time more people will get upset with them and they will get the boot and they will go elsewhere or start a new identity until outed. I am Willys every where, I don't open new identities just to hide from my past......IMHO, IF you are multiple people there is a reason for it......you are hiding from either trolling and baiting or you are worried about security. But people who open multiple identities on the same site are trolls IMHO, as there is no other reason to do so in the begining, is there?...sorry I'll fall off my soap box now......see how easy it is to get distracted.....damn!!!
Just a thought.......hope it helps...Merry Christmas .....
