Rule 2 of the Community Rules (https://nabzclan.vip/threads/48/) bans posting, requesting, trading or linking to:

• cracked or pirated apps and paid-app files
• licence or activation keys
• leaked or revoked signing certificates
• anything made to get around a paywall
• tools whose purpose is to strip copy protection (DRM, FairPlay)

Posting leaked or stolen certificates, keys or paid-app files after being told not to goes straight to a permanent ban, per https://nabzclan.vip/threads/46/.

What is welcome: help with sideloading and signing your own apps with your own tools. The rule text says that line is what keeps the forum online.

If you are unsure whether something is allowed, ask in "Questions about the rules" (https://nabzclan.vip/threads/42/) before posting.
