There is no particular way to give a certain bottle, but rather it all depends on your reputation and reputation power.
Your reputation determines which bottles will be present on your userinfo.
- After 5 positive rep bottles you will start gaining highly positive rep bottles instead.
- Likewise, if you are really evil like EKB, you will start receiving highly negative rep bottles after 5 negative rep bottles... but no-one else is that evil.
- If a users reputation balances out at 0, the user will have balanced reputation.
- If a user has turned their reputation off, it will show as disabled.
The more reputation you gain, the more bottles you will receive and the higher your reputation power will become. People with higher reputation power have a stronger influence when they give a user positive rep. Now, as for what the specifics are for a user to gain a new bottle and for their reputation title to change,
those are shrouded in mystery... but really, I do not know.
