Perhaps the owners/managers/software gurus at Marriott Rewards Insiders could put a temporary screen hold on all bookmarks that are merely ways to link us to often pirated television shows, or other media ads. Doing this would send them to a holding pen before posting and save us the time needed to report the abuse.
There might also be value in tracking down these perpetrators to determine if they actually are or should be members of Marriott Rewards, since some of the same names (often key repeats such as gfgfgffg, etc.) keep popping up. I note that "guest" is now an acceptable name for creating hotel reviews, so naming seems to have become almost like "anonymous."
