You gotta report it

Well if you don't report it via the Abuse Report, no one is going to do anything.   Have you changed your password?  The only way someone can use your account is to guess your password.  If someone is logging into your account, you need to be taking action instead of posting here in the forums.

What to do if your account is compromised

Your account may have been compromised if:

• You can't access your account.
• You suddenly notice a reduced available balance on the payment source you have on file.

If this happens, contact us immediately!

Here's what to do:

1. Go to the Second LIfe Help page and log in if you can. If you can't access your account, use the Forgot your login information? link on the right to recover your username and reset your password. Then log in.
2. On the Second LIfe Help page page, click the Contact Support link on the right.
3. On the next page, click Submit a a Support Case form.
4. Under What type of problem are you having?, select Account Issue. A second dropdown appears.
5. Under Account Issue, select I believe my account has been compromised.
6. Fill in the rest of the fields as directed.
7. Click Submit.
8. Check your email for your case number.
9. Call our fraud number: 800-860-6990.

Once you do this, Linden Lab will place your account on hold and investigate the relevant transactions. This may take a few days. Once we have concluded the investigation, we'll send you an email explaining our conclusion and the action we will take. Note that all transactions involving Linden dollars are subject to Linden Lab's Terms of Service.

You either let someone else know your password or you clicked on a phishing site that spoofed SL's own web site and stole your login information.  Either way, if you haven't already changed your password and reported that your account was compromised, it may be too late.  Reporting it here doesn't do any good.  There are no Lindens here, so there's no way they can know that there's something to investigate.
