How exactly did you merge this site (and what kinda site is this?) with your forum?
Are you 301ing for example?
When did you switch to Xenforo? Maybe it is the URL change which is causing your forum threads to get deindexed from Google?
"mamiakimo" drop in ranking is from after merging the new website to your forum?
People want to go to useful sites.
These sort of careless generalisations simply don't help, or match the information that's out there. Within most subjects there's age-dependant and ageless content. Even in the most modern ones like 'tech'.
