I had seen many people only posting bounty reports for months and years so I guess there is no problem if you are using your account for that.

But since the introduction of merit system, you need merits along with activity so you maybe stuck with newbie status forever unless you are buying or abusing merits which will get you red tag as well.

So decision is on yours, but don't post bounty reports on bounty threads if they never asked for that it is also can be a reason for an account to get banned.
