I think the better question is why do you have so many urls that look like this?
Code:
https://www.redhotsweepstakes.com/css.php?styleid=29&td=ltr&sheet=css_b_post.css,css_b_post_control.css,css_b_post_attachments.css,css_b_post_notice.css,css_b_post_sm.css,css_b_comments.css,css_b_comment.css,css_b_comment_entry.css,css_b_userinfo.css,css_b_meter.css,css_b_inlinemod.css,css_b_bbcode_user.css,css_b_event.css,css_b_link_thumbnail_list.css,css_b_thumbnail_nav.css&ts=1534275959
There are at least 9 extra long requests like that, that are 404'd meaning that they're not found.
