A lot of people seem to do this. My threads get knocked down to page five pretty quickly by my experience.
I don't think that the forums are pandemonium because of it.
It is better to bump up the thread by the time it gets to page 5 than to let it keep going to higher pages; because if I did that, my threads would be absolutely buried in the rubble.
Note that I usually don't bump them up when they are on page 3 or 4; but I wait until they get to page 5 or later to hump them up again so that they can at least be found in the first five pages of the forum.
I don't think you understand how this forum works
there are threads that have literally gone on for YEARS and NOBODY 'bumps' them up...many go for several weeks
when people are interested, threads keep going. when interest lags, a thread fades off without ceremony
just thought I would drop by and offer what is easily observed as a consideration regarding your apparent decision to keep a thread going that has basically just ... gone
