Feedback and suggestions

There's a reasonable use limit of 50 messages per day for all users. This is to prevent spamming.
It still allows you to send 350 messages each week.

The social or combined upgrades allows you to view unlimited messages, instead of being restricted to 7 views per day.

Please see my post in the other thread.

Everyone has the same amount of message views unless they've upgraded. There shouldn't be anything different about your account.
