Please increase rate limit for new users asking questions to one used at Stack Overflow (1 per 90 minutes)

Question

As September is coming, site is getting spammed by zero effort homework dumps.

Particularly passionate spammers even drop their garbage at us at highest rate allowed (today examples: 1, 2, 3, 4 - 10K links). And prior examples are not an isolated incident. As pointed in comments, next day after posting this request we've got yet another example separated by 10 minutes: 04:27, 04:38.

Can we please throttle spammers activity by raising rate limit the same way as it was done at Stack Overflow, ie to 1 question in 90 minutes for users with less than 125 reputation?

_{Side note, given that one of the spammers in above examples also has accounts at Code Review and Code Golf, it probably makes sense to consider similar limits for these sites as well.}

• Questions are now rate-limited to 1 per 90 minutes?

  If you need to ask questions more than every 1.5 hours, you probably aren't putting enough thought, time or both into your questions, which isn't fair to us, as it diminishes the perceived quality of the resource we're working very hard to build and maintain...

  It's a bit unfortunate for those that do ask good questions right off the bat, and bless you if you're in that very small minority - it won't take long for you to establish yourself, perhaps just one question could do it...

• Open letter to students with homework problems

  ...If your question on Programmers.SE is just a copy paste of homework problem, expect it to be downvoted, closed, and deleted - potentially in quite short order.

• Programmers.SE and the Summer of Love

  Responding negatively to those folks who copy paste their homework assignments is just a waste of time.

  These people don't care how you react; they're looking for the one guy that will actually do their homework for them (some people will). Consequently, your negative comment will have no effect on the OP, and will only succeed in irritating your fellow community members and alienating new visitors to the site.

  A better response is to downvote the question, and cast a moderator flag with a custom explanation, like this:

  Request for speedy deletion: this question is a copy-paste of a homework assignment, with no effort on the part of the OP to do the assignment himself.

Answer 1

For a couple of reasons (discussed in this post at MSO) rate limit for new users asking questions is now set to 40 minutes at Stack Overflow, Programmers and network wide. More precisely,

1. The new-user ask limit is now one question every 40 minutes, network-wide. That means only 1 question every 40 minutes on Stack Overflow, but also means you'd need to wait 40 minutes after asking a question on, say, Woodworking to ask a related question on Crafting or Home Improvement. ...it also means you'd need to wait 40 minutes after asking a question on Stack Overflow before asking a question on Programmers.

2. Rolling rate-limits kick in faster. Like, immediately. If your first question is downvoted and you try to ask another one 40 minutes later, you'll be forced to wait at least a day. That's potentially very harsh... But probably also better than penalizing everyone for the behavior of a few. We'd always intended rolling rate-limits to supplant the new-user rate-limits, and this will hopefully allow them to do so...

Though not precisely 90 minutes as requested originally, to me above seems to be good enough to qualify as status-completed.

Answer 2

It has been clarified through comments that this would be applied per-site, so someone posting on Seasoned Advice wouldn't interfere with someone else posting on Programmers. With this clarification, I support the proposal, at least on a trial basis.

But if traffic on Programmers increases anywhere near Stack Overflow levels, this would begin to interfere with on-topic use of the site. The 90-minute policy at Stack Overflow combined with the exhaustion of IPv4 addresses has already caused problems for users behind network address translation (NAT). When you have the same IPv4 address as another user of the same Stack Exchange site, it can be tough to squeeze in your question when others are waiting for the same 90-minute window to reopen so that they can squeeze in their own questions. See, for example, the question "Error — 'you can only post once every 90 minutes' but I haven't posted in days" by Bryan on Meta Stack Overflow.

Why might people be behind NAT? Some people access the Internet at a school, office, or public library, which typically has one Internet access subscription with one IP address. Others use an ISP that puts multiple subscribers behind one IPv4 address using carrier-grade NAT. CGNAT is common in countries with smaller IPv4 allocations and on cellular Internet.

Comments to the answer to Bryan's question recommend subscribing to cellular Internet access and asking the question through that connection. This ignores cellular CGNAT as well as the added cost of a subscription to cellular Internet access. I thought not having to pay for ExpertS-exChange was why the Stack Exchange network was created in the first place.

Thus without the ability to ask or answer questions before 125 reputation, a new user would have to farm rep by suggesting edits and have 62 accepted just to be able to use the service as intended.
