What are your ideas to solve the problem? There have been many made by others on this thread, none which seem to fully address the issues.
There have been many mentions of how the abort limit doesn't actually solve the problem. If the goal is to stop people from getting almost unlimited goods FP, then GBG definitely needs to be looked at. I think
@CDmark ran the numbers on GBG and found that you can get more there than you can with RQs. Stopping people from "exploiting" RQs (Ok, seriously, can someone please post a link to where Inno explicitly stated "exploits" as the reason for the 2000 abort limit?????) just moves people from one exploit to another. There's no way to define "exploit" that limits the problem to RQs. Since there are other exploits in the game, it's simply unfair to clamp down on just one of them, and in doing so, Inno has not "fully addressed the issue."
Secondly, I would contend that in the same breath as naming "exploits" to be the reason, Inno also stated that there were issues with their servers that they were addressing with changes to RQs. I've noted multiple times that, in the kindest possible way, much of the code for this game is absolute crap. If they're trying to balance server loads, there are countless other changes they could make that would make the game better for everyone instead of making the game insufferable for a small number of people. Again, since Inno hasn't officially stated anything about the 2000 abort limit, it's only logical to conclude that it is at least in part due to server issues, and those would be much better addressed in other ways.
Another solution is to, instead of limiting the number of aborts each day, limit the number of completions you can do for each quest. Some are limited by the size of your city in certain ages (e.g. you can only fit so many Butchers in an Iron Age city, and you can only collect so much gold a day in the correct increments). Limiting the number of aborts forces you to plan meticulously to optimize everything properly to get in as many quest completions as possible. Since the "Collect XXXX coin" isn't a quest that's being "exploited," don't count that against me when I skip it. There are obviously quests (mainly UBP) that account for most of the "exploiting." Cap the number of times you can complete that in a day instead of the number of aborts.
Change the 2000 abort limit for different ages. In Iron Age, there are a minimum of 7 quests to abort for a full loop back around to the UBP. In other ages, it's only 5 quests. Players are being punished more based on the era they're in. In Iron, you can do 285 quests, while in Industrial you can do 400. That's not cool.
Someone else mentioned other ways to make the current limit more palatable. Currently there's a hard reset at midnight. There was a suggestion made as to how that could efficiently (minimal server resources) be made into a rolling 2000 aborts. If I abort 2000 quests between 11PM and 12AM, the clock resets and I can abort another 2000 quests right away. However, a rolling time would keep me from aborting more than 2000 inside any given 24hr period.
To sum up, Inno has not fully addressed the issue. Maybe for now, but not long term. The burden should not be on us to fix the problem for Inno. This change is not fair, and we are trying to find ways to make the change less painful. This can be done by either making the flat 2000 abort limit more fair for people in different ages, raising it 4-6000 so that only bots are really affected, etc. The other solutions are ones that (possibly) fix the real problem (again, some official communication from Inno would be fantastic right about now) by resolving their server issues instead of just telling people they can only play the game so long each day. The 2000 abort limit is a poor solution to an even more poorly defined problem, and we're trying to redirect this "solution" to other areas that actually make sense when you take a wholistic look at the game.
