Welcome to the Q&A Forum

Unfortunately i share the same thought about this mess.

1. i already tried

2. gonna do some work on this and hopefully get result.

I provided you the url in a PM

The spammy forums are ALL different urls BUT with the same software.
Yes i only exchanged like 75 links myself BUT i'm pretty sure there are about 4 times more all around the web, spread by people visiting my site etc etc. Just like people post links to youtube on external sites, but nothing to worry about, this is normal..

You don't have to register to post a response on those forums btw. A real spam heaven for spammers. Created ONLY to spam.
It is clearly a bot who did this, all posts made are similar, only the title of urls are used different.

I don't think any human would spend time doing this unless it was a very desperate webmaster who tried to kick me out of results.

from over 100 links i discovered only 2 were linking to an internal page. I removed those internal pages already but i'm afraid the direct homepage links are hurting badly.

Hello Ryan,

First of all thank you for your valuable comment.
All responses i had so far on many other forums were "you must be a spammer" or "it's your own fault" based on nothing. (probably lack of intelligence from the one who responds)

Anyway,

I can say 100% that in over 6 years i'm running my site i never submitted the site to any free directory.
I have never hired anyone related to a seo company or any other link builder.
Also never submitted articles to blogs or other stuff related to submitting.

I don't own other sites offering similar content but i do trade traffic with other sites offering similar content, some of these partners (i call them partners because i do business with them since i started this website years ago) also link to me with "follow" links.  
I probably have about 75 of these links, all gathered in a time period of over 6 years.  75 links spread over 6 years should not be something to worry about in my opinion, especially when these sites are mostly quality sites too.

All these other sites i do business with have a same way of doing business. It's all about sending traffic to eachother, creating content and offering those to visitors.

All these sites i mentioned are still ranking page 1 for the keywords our niche is based on exept i'm the only one not in top 100 right now (While i was ranked in top 3, if not nr 1, for over 6 years)..

That is why i think the reason why only my site got hit are the 150 (spam)forums i mentioned before.

Thanks

Hello,

I'm one of those people that got the "unnatural links" message from google.

Since i run my site from the very first day and always was a one man business i know all the ins and outs of the website.
Basicly i have  never ever used a seo company to submit my site anywhere.
Never ever i used any shady tactic to get better ranks.
The only thing i did was trading traffic/links with real active websites, being daily updated, high traffic, etc etc.

So. After i got notified in webmaster tools i started digging into a list (provided by webmaster tools) to find out why i got this message (meanwhile i lost 75% of my se traffic in past 3 months)

After searching for hours i found out that in the past 2 / 3 months my site has been spammed on about 150 forums (completely dead forums with nothing but spam on it)

There was no logic at all since my site got linked with the most ridiculous and unlogical word phrases.  
My site is adult related and all spam links contained word phrases like "bangladesh mobile"  or "rock girl"  or  "animal abuse" or "ringtones" etc etc.

if i ever would be so stupid to start spamming my 7 year old strong business i would at least use titles that would make sence.

anyway.
I can't do nothing about these forums, i don't own them, i can't erase them and if there are any owners, they simply don't respond.
I made a list of all the forums and send it to google but the only response they come up with is "there are still unnatural links". I hardly believe they did anything with that list i send them.

I don't know what else i can do and was hoping that somebody could advice me on what to do here besides sending google messages on a daily base.

cheers
