You'd have to understand how vBulletin works, to understand the difference between how a post saying "thanks" is manipulated by the program, how "Reputation" is handled by the program and how the "Thanks" addon handles each instance of a thankyou.
There is a huge difference in how much bandwidth and system maintenance is used for each.
When a site becomes popular and has several hundred posts per/day, bandwidth begins to have impact on site costs, speed and maintenance.
The largest vBulletin site on the net is a "Jeep" site, and has more than a million members and thousands of posts per/day. That's the other end of the bandwidth issue.
The data of posts, members, threads, scripts, PMs, and all the counts of those features makes a lot happen behind the scenes that members don't see. Database cleanup and maintenance also uses bandwidth between servers.
The "Thanks" addon lessens the amount of data that has to be managed. It's a substantial amount of data on a busy site.
