Disavow Tool any good? Google are killing me...

Hi Guys,
I've been in this business for more than 5 years, this is how I make my living.
I have more than 30 games sites, some are good and unique and some are just ok (for example "flight games")
But during this year, most of my websites are dropping.

I have done many types of link building, some are black hat, some directories, some articles, some user profiles.
but there are lots of white hat links as well.

Any advice from anyone with experience in this?
I have manually built links for one of my websites for the last couple of months, links that are definitely white hat but still - no improvement - only droppings.

Is the Disavow Tool any good? anyone worked with it successfully?
and if so - should I remove any black hat stuff?

Thanks.

nuthing about Black hat stuffs bro. All are shit Big G makes me too much of angry on these days. Dropping so much of backlinks damn nit.

What keeps people from automating the disavowal tool?

I've never used it myself, though I've read it does nothing. I doubt it'll do any damage so you're welcome to try but I wouldn't count on it or anything.

so what can I do to get better ranking?
I tried a couple of stuff people are selling here for rather small and new websites, no results at all.
Nothing seems to work these days...

If you were penalized I'm not sure what to do, but if you kept using the same anchor text to your sites that are dropping as a primary keywords, perhaps you could diversify those with other backlinked anchors.

google will not consider a disavow submission unless you show them you have attempted to get the links removed

trust me i have tried over and over again and the only time they took it into consideration is when google reviewed my reconsideration request after using a link removal service called linkdelete

it took me months to get the penalty removed though so make sure you are seroius to clean up the websites backlinks
