This is not considered sexual abuse. I haven't went to the link provided (and won't). It appears you (or the person in the pic) allowed someone to take a pic while only wearing a bra and the pic was shared. I would start with a complaint to the blog writer, then the company who is actually hosting the blog, and then, if no resolution I would call your local PD to inquire how you may be able to get it removed.
Having said all that, I cannot help but wonder if this is some kind of joke.
Pretty stupid to come on a PUBLIC complaint site to complain about a pic on some obscure blog no one has ever heard of. Are you complaining the pic is there or advertising so people will go look? Why would you complain that you do not want people to see the pic and then give the EXACT url address for people to go look at it.
Before you posted this, very few saw it in comparison to how many have probably seen it now.
I would love to get a reply from the complaint writer (roneet) with the circumstances regarding this pic. If the pic truly is out in the public through no fault of the woman in the pic, that's a shame. Even IF it was posed for (the pic taken with permission), there ARE steps to have it removed.
*I just noticed the person seems to be from India so I opened my mouth too soon. I have no idea what the laws are in India regarding the right to privacy. I would still advise the person to take action against being exploited rather continuing to be a victim of the blog owner. If all else fails, get the pic copyrighted and tell the blog owner they don't have permission to use the photo. In the US, one can sue if they would continue to exploit an innocent victim (again, I know nothing of India copyright laws--just tossing ideas out that may belp).
Best of luck, if indeed you are being victimized.
