Acceptable Use Policy
We do our best to provide the least restrictive rules while keeping the integrity, reliability and legality of our services. Therefore, we ask you to abide by the following general ruleset:
- No pornography involving minors/CSAM. This includes videos, images and audio, AI generated or not. Starting 2 May 2025, this also applies to fictional depictions of minors.
- Do not perform DoS/DDoS (Denial-of-Service/Distributed Denial-of-Service) attacks from our servers. C2 (Command-and-Control) servers for botnets and stresser/booter panels are also not allowed.
- Do not send mass unsolicited outgoing mail (spam), host phishing pages, mass port/vulnerability scan, or anything else that can get your service’s IP listed on Spamhaus.
Outside of these policies, you must also follow the laws of the country your service is physically hosted in, as well as the laws of Romania. We expect you to do your research on any unknown terms or laws beforehand. While we usually (see rule #1) won’t nuke you at the first complaint, ignorance is not an excuse for severe policy or law violation.
User-Generated Content
If you plan on hosting user-generated content, we expect you to moderate it in a way that ensures illegal content is removed before any complaints reach us.
The best way of doing that, besides monitoring the content manually, is having a functional contact form or email address, with a link to it on every page displaying the content. If you make it clear that you host user-generated content, law enforcement and child protection organizations will usually contact you first before contacting us.
Resource Usage
You can burst to 100% of the CPU, RAM and disk space allocated to your service. Sustained CPU, disk I/O and network I/O usage is subject to fair use limits because these resources are shared at the node level.
The current suggested daily fair use limits are:
- CPU: 50% of allocated vCPU capacity, averaged over a rolling 24-hour period
- Disk: 20 MB/s (megabytes per second) average
- Network: 100 Mb/s (megabits per second) average
These limits are not set in stone, but, as per our TOS, if we find that you are using up too much CPU, disk I/O or network I/O for a considerable amount of time, we may set a hard limit on our side for your VM.
The CPU fair use limit goes into effect on 11 May 2026. Until then, the previous CPU policy remains in effect.
I2P/Tor
I2P and Tor nodes, including exit nodes, are allowed.
In the case of Tor exit nodes, we will treat abuse reports with more leniency, one of the important exceptions being email spam (default Tor exit policy blocks email ports).
Don’t use exit nodes as a free pass to abuse, reports from exit nodes are still manually analyzed.
If you run a popular node, keep an eye on your bandwidth usage, and if necessary, set a bandwidth limit on your side.
Public Proxies/VPNs
Unlike Tor exits, there is no accurate list of public proxies and VPNs that network admins can block if they’re concerned about incoming abuse.
Because of this, running public proxies/VPNs is not allowed on Kyun, and because of the bandwidth fair use policy, it’s not a good idea either way.
