Legnicka progress

Hello,
I had started using vb and of course vbseo on the 7.10.2008
I had decided to use this sw in case of comparision to the IPB and CSEO that I'm using on the other site for over 1.5 year.
Legnicka is very small community - it's about new building in Wrocław and our close neighbours.
when we stared vb there were 1 year SMF with some small ammount of links to it and indexed about 120 pages by google.
Now after 3 months we have about 3000pages indexed, totall ammount of users online is even not tripled but 6-8led
Adsense gives us more income, and seems it was very good movement to change from smf to vb/vbseo.
Now we are on the third place in google for our name, what was needed and was achived - over the company that sell our flats

Unfortunatelly we have a big issue now - crazy ammount of spam and spammers. I don't know what is the real reason but this is a nightmare for me. Earlier on smf or even now on different form on IPB/CSEO that is page ranked 4 and I got over 100k unique users monthly I don't have spam, but here ...

In general I think vbseo was good investment

now after movement to the 3.8.2 and vbseo we had droped to the 300 indexed pages :(
