It's your choice to leave. It seems a bit precipitous to me, given that the folks here are still here, but before you go, can you show the science behind your assertion of limiting? I have had multiple windows in multiple browsers open to the site simultaneously on multiple machines in my location and not seen any evidence of rate limiting or security dropping of any session. If you are going to heave that rock, it should be possible to show the mods how you came to that conclusion. Just saying "it doesn't work" is not helpful to them to find and fix any such issue.
It wasn't pointedly laid out, but my previous post shows it...
I have two machines that I operate at the same time. One is in one location with an Internet connection and the other is in a second location with its own Internet connection. The second one is one that I connect to remotely from the first location. I operate both simultaneously.
Connecting from the first machine and attempting to send PM's results in error after error. At some point, the site just gets "mad" at me at drops my connections. The TCP stack on this machine shows "SYN_SENT" and the browser simply says "Connecting..."
While the first machine is spinning in La-La Land, the second machine connects right in and keeps going browsing, transitioning pages, and doing whatever I ask it to do. During the entire time, I keep refreshing the page request on the first machine and it never connects. It takes seemingly 15-30 minutes before the connections will come back.
If I reverse the usage of the machines, the problems reverse as well. There some sort of controlling system that lives between the users and the actual web server and it's impacting the use of the site.
This is a big part of what I do for a living (and have done for a very long time). I deeply understand web servers, db servers, application architecture, Internet connectivity, networking, App Delivery Controllers, Web App Firewalls, and all sorts of other related items. I tried offering assistance when a plan was being discussed to handle the pending shutdown, but no one was interested in what I could offer. Now it seems that some decisions may have been made about "what to do" with this site that are impacting the user experience and all kinds of quirky little issues are being reported. Since absolutely nothing has been shared about what's actually happening in the background, I can only speculate using my 30 years of troubleshooting experience as to what is likely going on.
