NO! All you need to do is push that like button and possible refer to the thread in other threads if warranted.
Bumping is the equivalent of shouting to get your point across. Using a bullhorn to draw attention in a church is not the way.
If comreps are not responding to a thread, it's because the devs simply have not yet conveyed their response to the comreps to give to us. Sometimes this can take weeks of months, and only LIKE count will push a thread further on the notice list.
