the level up requirements to be rated by a top ten or a top 250 "hottest member" requires being rated by a "lifetime hottest member"
on your level up page the description includes a link to a list. the same list can be seen by clicking the "hottest" tab at the top left of your page and a drop down menu will appear. the first selection is for "members overall," and if you click that option you will see there are two columns. the left-hand column is for "hottest lifetime members" and the right-hand side is for the week. the level up requiement is for those peeps in the left-hand column. (you may notice that the lifetime top ten members have a bright red name, while the weekly "hottest" have a darker red name.)
