According to
mprep rule number 13
In his rules and guidlines. It is clearly stated that bumping the thread will be limited to
once per 24 hours.
13. Bumps, "updates" are limited to once per 24 hours
So i think this behavior will not be tolerated. As if we are following the exact rules.
When companies use thread bumping services, they break that rule (usually) and they don't wait enough 24 hours to make next bumps. Obey that rule means you don't have to use thread bumping service, so in contrast when one company decides to use that service, they automatically accept rule breaking at the beginning.
