Were any of your characters maliciously transferred, renamed, re-customized, or had their race/faction changed? If so, it's best not to gain any progression on those characters, as we'd go about reversing the malicious transactions by actually rolling them back. This means that your character would get rolled back, too. As a result, any new items, currency, and/or achievements that you gain now would just be lost during the roll back.
If no characters were affected, then happy gaming! Please feel free to continue leveling/progressing any character that was not a victim of a malicious transaction. It won't throw off our groove at all. :)
