Hi, I am doing SEO for a website of local cleaning business. This website has a forum which wasn't maintained well before they handled me the website. During this time a lot of spam topics and forums was created by spammers (some of those topics was adult/gambling related). These spammers also created lots of toxic links(according to ahref total 4.5k). I have already deleted all those replies/topics from the site and disavowed most of those backlinks. Its been around 2 months I have done those work but the website still not showing expected result. Is there anything else I should do? Thanks.
