There has been "game breaking" bug abuse since time immemorial. I personally remember several cases, that I won't even bother to list here.
And from what I have been reading, there have been TONS more ever since I jumped ship, and nope, it isn't ever going to stop. It is "too convenient".
It is too convenient for the "smart ones" so they can get ahead of the competition, except... no one really gives a single flying duck, because there is no one left anymore except for a sad bunch of (mad?) delusional cows, either fat or skinned ones.
I certainly do remember one truly glorious "bug" that was "conveniently" abused, back at the time, and turned certain chaps to insta-billionaires. Yep, while at the time I (and several others who were quite active - and with their real money too) had been patiently farming lants (for example) for about 3 years in order to have a "fat account balance" of 300 mil or so, which was considered disgustingly filthy rich (not to mention all the MALLS sold too to add into those lants). Just an example. And all that was "conveniently" written off just with one "bug", and all those chaps suddenly could show off their 2-3-5 billions and so on and forth.
This is how lil old beloved ReQQ worked for years, except the whole "process" has now been elevated to "high science" status. What the "management" fails to realise (because they surely KNOW and always allowed this kind of dogsh*t to happen) is they can't fool everyone and forever, except maybe for the aforementioned bunch of "mad cows".
Just another great plan to keep the game flourishing, it really shows, doesn't it?
