@PatrickHofman someone found a bug with accepting answers. nicael took it much further and abused it in a way that caused two users in MSE to lose thousands of reputation points.

Patrick Hofman

Okay. That isn't fun. Nicael loves to break stuff, but sometimes it is too much. Like now. Unfortunately.

Jan Dvorak

Q: How did this question get two accepted answers?

This question appears to have two accepted answers! How does this happen? Here's a screenshot in case it changes:

Jan Dvorak

Thanks. Was looking for it on MSE

Shadow Wizard

@JanDvorak yeah for some reason it didn't reach MSE though it affects all sites

nicael decided to test on MSE, and "only" with two guinea pigs but still.... suspension was well deserved

Jan Dvorak

8:06 AM

Totally

Who were the victims?

Patrick Hofman

Unihedron it seems meta.stackexchange.com/users/266094/unihedron?tab=reputation

Shadow Wizard

@JanDvorak Inf and yours truly

@PatrickHofman oh, missed that!

so make it 3 victims

Inf was dropped to 1 rep, and I lost ~20k or so

Patrick Hofman

Sorry, but I don't get how it worked. Wasn't there a check on the user accepting or so?

Or unaccepting in this case?

Jan Dvorak

ok, this isn't cool

Shadow Wizard

@PatrickHofman exactly. No rate limiting in the server side.

@JanDvorak The victims included @Roombatron5000, @Unihedron, ShadowWizard and me. We lost thousands of points. I was reduced to 1 rep. I got most of my rep back now.

Thanks

Shadow Wizard

@James no, but following a chain of events, the bot ended up posting messages by nicael, which people here found annoying

SPArchaeologist

@James so did I Saturday. Twily, my friend... You really believed Celestia didn't that on purpose - again?

Infinite Recursion

@nicael was very sporting as always (even after being suspended), he even tried to help me by suggesting ways via which I could trigger a recalc and get the lost rep back. He didn't rant or write a blog like other suspended users. But this suspension workaround bot and reports thing isn't so graceful IMHO. Thanks nicael for honoring my request and stopping.

see how it says Reputation (1)

Infinite Recursion

@SPArchaeologist He wrote JS commands to trigger accept and unaccept of answers multiple times. Every accept gave us +15 and every unaccept gave us -15. The number of unaccepts were more than the number of accepts, hence draining uni and my rep to 1.

Finally the voting has been completely reversed. It took 2 days and the rep came back in chunks. See my reputation meta.stackexchange.com/users/245167/…

Unihedron

in Maid Café (メイド喫茶) on The Stack Exchange Network Chat, 2 days ago, by Unihedron

but if you accept answer A, and then accept answer B, you'd unaccept A without actually doing it, and that's where the bug is

^ the bug in a nutshell

add race conditions and an insane amount of requests like nicael used and you have a rep nuking engine

SPArchaeologist

race condition = sending multiple requests in a very short amount of time so it ends up doing 2 actions at once which are normally not compatible?

We knew he would stop after some time because it was nicael and we trust him. If someone else uses this exploit, it can lead to bigger problems. This is perhaps the best exploit @nicael exposed in the recent past.

@InfiniteRecursion Allow me to define ethical hacking: Performing penetration test when authorized. Nicael's use of spam requests weren't authorized or well-reasoned, so SE suspended him for that reason.

Therac-25

The Therac-25 was a radiation therapy machine produced by Atomic Energy of Canada Limited (AECL) after the Therac-6 and Therac-20 units (the earlier units had been produced in partnership with CGR of France). It was involved in at least six accidents between 1985 and 1987, in which patients were given massive overdoses of radiation. Because of concurrent programming errors, it sometimes gave its patients radiation doses that were thousands of times greater than normal, resulting in death or serious injury. These accidents highlighted the dangers of software control of safety-critical systems, and...

@rene The discussion was retriggered because users are now helping nicael avert suspension and justifying their actions. Victims speak up in such cases.

I hope SE reduces the rep of the helpers to 1, or suspends them for a week for helping users avert suspension.

We should really leave that to mods and CM's

Infinite Recursion

Yes, I agree.

bummi

blacklist candidate wecareskincare.com

Unihedron

@InfiniteRecursion I honestly think that goes too far, mostly because the helpers acknowledge the situation and stopped. After all, the penalty box is used over harsh punishments like account deletion so users gets a chance to recognize what they did wrong and stop doing it during their account vacation, same with what reducing their rep would otherwise do - toss the red light signal, which isn't even effective now that the helpers stopped.

In most cases a formal warning is enough over software restrictions.

Then again, nicael is one who would only be stopped by software restrictions, so I'm not justifying their particular behaviour against the suspension.

Jan Dvorak

Better: write single-threaded code in Haskell, then sprinkle par where appropriate. Worst case you'll only reduce the performance as the runtime tries to realise it shouldn't paralelise despite your suggestions.
