Yet they are scared of giving explicit answers for number 2 and 3.
I'll answer:
- It is allowed to own alts.
- How many alts will one own and it will become a farm?
- Is farm accounts without merit sharing, cheating campaigns or contests allowed?
2. The word "farm" is used for people who run different accounts for earning money. I don't think there's a hard limit: 2 accounts isn't a farm, 20 is. Somewhere in between is a gray area.
3. Yes. From the forum rules' perspective, I've never seen anyone banned just for owning many accounts. But if one of them gets banned, the rest is guilty of ban evasion. The Merit sharing and cheating won't get you banned, so you could say it's "allowed" from the forum's perspective. But that's where the "alt farm hunters" come in with the red tags.
