When looking at all these preventive measures I immediately want to play in Solo again - and if only for not supporting this nonsense.
I do understand all of the above and certainly could do that. But seriously, I had to think trice and ask myself: All. that. hassle. For what? Just to escape an interdiction? Is that what people are trying to talk me into Open with? Before someone wants to paint me as the drama queen, recently I actually played a few days in Open again, though I think I was just gambling while flying my mining Conda that's certainly not PvP ready and sometimes brimfull with painite. All it did was convincing myself that the griefing and ganking situation isn't as bad as often misrepresented(?) on the forums.
I saw exactly one single hollow square during my last days in Open that vanished in the very moment I entered a high frequency (according to traffic report) system. Can't also be daytime as I'm playing on different daytimes, my sleep/wake cycles are very fragmented. This only can mean one of two things: either what I mention at the end of this post or the ratio of players in Solo vs Open is strongly towards Solo and not what Sandro stated back in the days that most players would fly in Open. Note that I'm not suggesting he was lying, situation could have changed over the time. I'm well aware that many posters say they would fly in Open, but then there still could be a much higher dark figure who either don't post here or just doesn't want to admit that.
The other possible reason why I rarely meet someone in Open could also be because I don't play with port forwarding, something that drastically seems to reduce the chance to meet other players. A few month ago I tried to set up proper port forwarding (and not just UpNP which also doesn't work for me according to network settings page), followed all the advice I could find, spend a few days tinkering, only to realize that in the end I had achieved literally nothing, nada. Just didn't work.
That's the whole Open shenanigans to me in a nutshell. Makes my brain crackle when I still hear about people dreaming of OOPP...
