Right, on with it then.

Why the hell are there hourly limits for notes.
I understand hourly limits for comments, a little less for upvoting, I don't know if there's one for favoriting,
But notes should be off limits.
There's a much less likley chance for someone to spam notes to wreak havoc than comments because 1. It's obscure-er 2. It's lame and 3. Its easier to get rid of.
Notes shouldn't have a limit because its the only tool for translation. Makes translators who are translating, say, a doujin have to wait a whole hour after reaching this limit to continue and finish the whole thing (fucking me, 20 minutes ago), but at that point, they've lost intrest.
Maybe there's a thing for priviliged users where they bypass this limit, but I think, it should be no limit for anyone. Maybe instead add the limit only for users who've gotten a warning before instead.
In conclusion, the hourly limit for notes is the worst possible thing to limit on this site. Translating is important and I spent way too long typing this forum post.

There were some serious cases of note vandalism in the past.

But still a chance nonetheless. It only takes one bad apple to spoil the whole barrel.

Priv+ users do not have hourly limits and trolls can simply create alt accounts to bypass their account limitations to abuse the system. That is why I feel spam protection is required.

Uh-oh, Seems there are appropriate answers, already.
But, Let me tell you what I think --- Afraid to say but my vote is NO. The reason is the opposite of what you are probably thinking.

There's a much less likley chance for someone to spam notes to wreak havoc than comments ... Its easier to get rid of.
... it should be no limit for anyone. Maybe instead add the limit only for users who've gotten a warning before instead.

Just look at this list: [Users ''listing'', Order = Note count]
I am sure You can find "Blocked" users, And how many spam notes did they leave --- 6953. (( Well, it is enough to call it havoc at this point, I think ... ))

- Have you thought about the possibility of such spammers appearing more ?
- Have you thought about the pain of the time of undoing/removing a ton of spam notes ?
I do Not think it would be easy or ""easier"".

Notes shouldn't have a limit because its the only tool for translation.

Also, Truth is, Users can also use Comments for translation.
Especially if users want to try to translate into non-English language on e621 the English site, They have to use - Comments instead of Notes.

In the first place, The number of Translators (who would hit the hourly-limit) is far less than the number of e621-users.
Given the existence of Troll, In my opinion,
Most users should have a limit for notes, and Only the really trusted translators should have Off-Limits.
(( Maybe the Translator you saw could be the trusted one ?　Though that's not for me to judge :| ))

Therefore, My vote for removing hourly-limit for every users is NO.

Maybe have a flag for known good translators? They only get reduction of limit for the notes? Like mentioned, there's not that many active translators compared to the number of potential spammers. A Boolean would be perfect for this? I agree that removing it for new users is no bueno.
