I doubt this will change ...but I am seeing more and more forums that prohibit bumping. I mention this, as I log in right now 9 of the most recent 10 posts are bumps. I find myself checking the forums less and less on the weekends, due to the high volume of bumps that show up then.

Other forums I frequent will post to users when they bump. IMHO it makes a good point about approving bumping with additional information that may be of value. Samples of their mods' replies look like this:
This is a reminder from the moderator team to avoid bumping threads, as detailed in the "Minor Problems" section of the Forum Rules. Bumping may bring your thread to the top of the forum display, but that's unfair to other forum members unless you have new information to add to the thread. Your post may have been edited or removed for this reason.
For further information and instructions, see the Reminders section of the Moderation FAQ. If you have questions, comments, or complaints about moderation, use the Contact Form.

Just a thought to ponder.
