The limitations of privilege are not an obstacle to be worked around, rather a symbol of the community's caution towards new users.
The first time you enter the Stack Exchange group of communities you are required to prove that your intentions towards the community are benign and helpful. This comes in the form of the New User Restrictions.
Helpful questions in comments are welcome, but understandably they're restricted until the community recognizes you as someone who has contributed, and hence understands their use.
Once you've become a recognized contributing member of one of the SE communities (rep > 200) you automatically get an extra 100 reputation in every other SE community you join to bypass these restrictions.
Long story short: Being to be downvoted for attempting to bypass the reputation limitations is to be expected. Everyone has to suffer these limitations at least once, so grin and bear it for the duration of their brief inconvenience.
