So, alright, I admit I'm writing way too much. Just see this as me being interested in the topic. I generally feel like a pledge is a good thing but it needs much more consideration than the one that's being done in the other post. That's why I'm nitpicking at everything here. I don't really have a solution for now but I think we could find a good one if we take a close look at the (possible) issues and then try to find a way to fix them.
Considering one of the mods actually did sticky the pledge thread I feel like it's not totally hopeless anymore to get them to be a part of this.
So, back to what I wanted to add. I just wrote the following and think I should say a bit more about that:
yansusustories An author might just have struggled with one project and that so severely that he couldn't even write an ending. Or he just wanted to have it pending for a while and was sure he'd find a good way to continue later on. Considering he's the author, I feel like he should have the right to do so.
So, this probably looks like it wouldn't happen. But I can say from my own experience that it does. I'll go back into story mode now because I feel that examples just make explaining these things and showing possible issues so much easier. Sorry for that 
Back in my home country, I had that one project I liked very much but got more or less negative (or at least not really positive) feedback for the second volume. I did have some issues in my work life, too, so I took my sweet time editing the thing (I'm talking about a traditional novel series here not a webnovel but it would have happened all the same if it was a webnovel, that's why I'm bringing this up).
Yes, it was just editing. I had actually already written the whole series then but I wasn't alright with publishing it just like that because it was honestly not good enough. Most of my struggles came from the reader feedback because I wanted to incorporate that, too, to make the novel more enjoyable for everyone else (an issue I've also experienced with one of my webnovels here, so those things can really happen). I couldn't do that. Because what I wanted for the series and what they wanted for the series were just two completely different things. That happens.
After a year went by (not necessarily too long for a traditional novel) I still hadn't managed to complete the edit because I was still struggling with the same issue. So, I decided to make it not a novel I'd publish but a free version on my blog instead. I did post the beginning in relatively short succession because I had managed to finish that in a satisfying way and honestly just wanted to get that thing out of the way. After that, I took some months (!) break again.
I still don't consider this project as dropped because I will update. It just takes a lot of time because I've got lots of other things to do and it just isn't a project that writes/edits itself fast.
This would be a project I'd get the yellow card for in the scenario of the pledge we've painted until now. But I feel like, as the author, it's my right to take a break and seriously consider all aspects before posting because if that volume doesn't turn out as I want the next one won't either. And that might be an even bigger problem because I'd lose motivation completely.
Now, I could have just ended the novel (as MasterRabbink proposed as a means of not dropping a novel, I believe?) just where it was, even if the ending would be crap. But, well, I had already invested several years of work into that thing. Why should I make a shitty ending if I'm totally capable of doing a good one? I just need time for that!
And I feel like I don't have to do that (writing a crappy ending just to have an ending) either. I'm the author. And the author should have the final say over what does and what doesn't happen in his stories.
Now to the conclusion:
This is probably an extreme example and, yes, I'm talking about a traditional novel here not a webnovel so you probably can't transfer all of that. It might have been different if it was a webnovel. But I do think that issues like authors needing a bit of time or a bit more time to figure something out can very well happen even here. (And honestly, they should happen because only that way will we get good novels in the end. If we always rush the authors then naturally we'll mostly get filler-filled novels that only follow the cliched storylines we can already recite in our sleep.)
So, it should be considered very well after which time a novel should be counted as 'dropped' and what kind of punishment is necessary because of that. Because not even considering outside reasons there could be reasons the author has that make it necessary for him to take a little more time.
A pledge of not dropping a novel has as its ultimate goal to make better originals and a better environment for the originals if I understood that correctly. If that's the case, then it can't be the purpose of the pledge to restrict the authors so much that they might even need to write a crappy ending just so they won't get banned. That's not a better original you get, that's just a worse book than you could have had and a frustrated author.
