I have a legit forum dedicated to programming. I stopped maintaining it for 4 months because I was in a remote place where there was no Internet. During that time many people spammed my forum for backlinks for just about every niche you can think of and Google has taken my forum out of search. I just got done cleaning out all the spam and banning the spammers. Is there any way for me to get back in Google search? I was on the first page for my keywords.
