I can't see any reports in the queue against you, nor does there seem to be any reported messages so not sure what the nuke was for. Try contact theymos to look into it. He can restore your posts if need be.
See, it's obvious in bitcointalk community that before an account is been banned someone might has reported any of he/her topic or comments with a concrete evidence of plagiarism, spamming and other rules and regulations of of bitcointalk community, so if really their is no evidence concerning the account, I think the best suggestion is to contact theymos before it will be late, as you said. because without taking a drastic precautions or measures the account will be banned till infinity.
