What about you? Are you read the forum post without log in while you have an account? Personally I always log into my account first because there's some advantages e.g. the brightness, knowing the opened/new thread etc.
Do you mean we can using multiple accounts in order to earn money as long as we didn't abusing the rules e.g. join with multiple accounts?
Having several alternative accounts is not prohibited, as long as they do not violate the rules of the paying companies themselves. I will say more, some bounty managers do not have a direct indication that alternative accounts are prohibited. Thus, it admits the rule that if there is no prohibition, then there is permission.
What to say about reading the forum without logging into your account, is also possible. Why not?
I have one account on the forum, and if I want to read the forum from my mobile phone, I do not log into the account from many devices.
