If you recently came off of a 25-game Chat Restriction, then, no, I'm afraid you won't get unbanned. Report rallying can be a form of harassment in and of itself, and it really doesn't do anything beneficial to call for reports anyhow - one report has the exact same weight as nine. You can report the player yourself, and it would have just as much effect as everyone else reporting.
If you reported him, he would get a punishment of his own for flaming - be it a chat restriction, a ban, or Honor progression being stalled.
All said, outside of what was mentioned before (previous punishments, etc.), you may want to provide your chat log(s) for peer review, so that we can point out where (if anywhere) you stepped over the line.
