About MMOMU.COM

mmomu.com is a MU Online private server list and knowledge base. We help players find trustworthy servers and help server owners get discovered — with fair ranking, clear opening dates, and free guides.

Every day we track upcoming openings, recently added listings, and the community vote toplist. Free listing is available after registration; VIP placements are optional for extra visibility.

Fair rankings with anti-bot voting

Rankings should reflect real players — not scripts. Here is how we keep the toplist honest:

Protection	How it works
reCAPTCHA verification	Every vote must pass a CAPTCHA challenge, blocking automated vote scripts.
One vote per IP per day	Each IP address can vote for a server once every 24 hours. Repeat votes are rejected.
Signed postbacks	Owners can reward voters via HMAC-SHA256 postback — spoofed callbacks without the secret key are rejected.

Server listings

Listings move through a clear lifecycle: opening soon with countdown, recently opened / live, and ranked by votes. Players always see rates, season, type (PvP / PvE / Non-PvP), and a direct link to the server website.

Owners manage everything from the profile: projects, servers, vote buttons, postback rewards, VIP, and statistics.

The knowledge base

Section	What it covers
Guides	Seasons from 97d to Season 22, character classes, wings, events, maps, bosses and gameplay systems.
Item database	Items parsed from game files — weapons, armor, wings, jewels and more, searchable by name and type.

FAQ

What is mmomu.com?

A MU Online private server directory with rankings, opening countdowns, guides and an item database — built for players and server owners.

How are rankings protected from bots?

Votes require CAPTCHA and are limited to one per IP per day. Abusive patterns can be blocked by the team.

Is listing a server free?

Yes. Create an account, add a project and your first server. VIP and ads are optional paid upgrades.

Where does the guide / item data come from?

Guides are written and maintained for the community. Item data is compiled from public MU Online client / server file structures.

How do vote rewards (postback) work?

After a verified vote with a username, we POST a signed payload to your Postback URL. Your script verifies the HMAC and credits the player — see Profile → PostBack.
