Clean Slate Glitch?

You have convinced me now, that it is a glitch. There is though, two points I have to disagree with you about:
1) You cannot use "common sense" to explain things. "Common sense" is merely a label, it is not logic.
2) You cannot predict the future actions of Nexon, as with your "possibility to create a 500 slot cape". As stated somewhere in the earlier pages, many of the glitches such as jumpcasting with mages or HP washing became features when Nexon let them slide. Why would they give you a chance to make "false" stats that give bowmen the same survivability as Mages?

I commend you though for typing this out, contrary to Felix and Opeth, who merely just stated that I'm stupid or dense for thinking logically.

Well, maybe logic is a better saying than common sense in this case, idk. The idea behind what I wrote is that you have to put yourself into a Nexon programmer's position and ask yourself whether the feature included was intended or not.

And for #2, I see your thoughts and ideas behind this. I think one should put oneself back into the programmer's shoes and ask whether this new unintended feature/glitch is made up in such a way that people using this feature may be effectively abusing the glitch (pickpocket-glitch, toenail-glitch and bigfoot-glitch as examples) and should be punished for what they did.

The other part of this, is to find out whether you're able to find out whether a person has been abused this glitch or not. (Which is the biggest issue, really) If you're unable to locate and/or the glitch is so extreme that it will kill maplestory as of today, the "only" way to fix this is by a rollback, I'd think.

Last part, as for chair jumping and spell-jumping: These are minor glitches in the game, which does not really make anything unfair for anyone. The spell-jumping may be discussed, though if I were a Nexon programmer, I'd think that this unintended feature was a bonus, and a "gift" instead of an issue.

So, is this feature/glitch, "no-slot scroll white scroll-scrolling", effectively abusive? I consider this to be the "hardest" question in this issue. Yes, it is effectively abusive, but a white scroll will save a slot anyway. Using a clean slate (which has a possibility of destroying the item as well) while using a white scroll, then add a scroll back on top later on has so to say the same effect as just using a scroll with a white scroll. The only difference is that you're able to regain a slot on an eventually bought item, work a scroll, and possibly earn a lot by doing so.

The other part (protection/spike), I'm unsure of because I'm unsure whether there's a check on their servers with the scrolls. If there's no check, this glitch will very dangerous for items, such as facestompers. You're able to give the items a lot of attack through the use of chaos scrolls. So, if there's no slot-check:
yeah, this issue should be addressed as soon as possible. Since Nexon-programmers (or technicians) has all the data in a database, they could eventually search up items having more slots, or worked scrolls, than possible. I do agree that this would be somewhat hard if they have no searching-algorithm yet, but that's the only way finding people effectively abusing this part of the glitch.

If not, I would address the issue as soon as possible, but not penalize for the error as it does not create too much harm.

If I put myself in a Nexon programmer's shoes, that is.
