Will votes on my answers/questions cast while I'm suspended still increase my reputation after the suspension ends?
All votes are associated to the post they are cast for. When your suspension period ends, your reputation will be re-calculated. This means, the votes on all of your questions and answers (positive or negative) will be counted, and the correct reputation score will be computed.
So yes, if you earn a few votes during the period, you will get credit for them. However, take note that if any votes were invalidated by the system, you will not receive credit for them, since they no longer exist.
If you want to try an experiment (I have no idea if this works while suspended), visit the reputation audit, and you'll see exactly what will be counted when your reputation is re-calculated after your suspension. I think your reputation will still show as
1, however you should be able to see the number of votes that will go into your score.
