RE: How Do You Work With Multiple Accounts?
First of all I think this is inevitable.
Working with multiple accounts always has this problem and no matter how careful you are there will be a mix-up one day. The best thing to do is to have different browsers as you suggested but even with this, you might end up making a mistake once in a while.
In your case I think you should always try working with the Incognito mood for accounts that you hardly use and using the main google account for the ones that you use on a regular
Now here comes my problem.
You have shown to us that it us normal for all of us to make mistakes once in a while and the problem I have with some mods and admins of some communities is that they never understand when others make these mistakes. They only tend to mute them without listening to reasonable explanations. Each time I see this I feel saddened because it can happen to anyone and then they end up destroying the good reputation the person strived to build.
Yes, I have already met this. I've seen people accused of using different accounts, even though there wasn't enough evidence that they were doing it for the purpose of fraud. In such a case, it is impossible to prove yourself right. The only way out is to leave such a community and write in another.
