With the increasing number of individuals accessing online child sexual exploitation material (CSEM), there is an urgent need for primary prevention strategies to supplement the traditional focus on arrest and prosecution. We examined whether online warning messages would dissuade individuals from visiting a honeypot website purporting to contain barely legal pornography. Participants (n = 419) seeking the site were randomly assigned to one of five conditions; they went straight to the landing page (control; n = 100) or encountered a warning message advising of the potential harm to viewers (n = 74), potential harm to victims (n = 65), ability of police to track IP addresses (n = 81), or possible illegality of such pornography (n = 99). We measured the attempted click-through to the site. Attrition rates for the warning message conditions were 38% to 52%, compared with 27% for the control group. The most effective messages were those that warned that IP addresses can be traced (odds ratio [OR] = 2.64) and that the pornography may be illegal (OR = 2.99). We argue that warning messages offer a valuable and cost-effective strategy that can be scaled up to help reduce the accessing of CSEM online.

随着越来越多的人访问在线儿童性剥削材料 (CSEM)，迫切需要初级预防策略来补充传统的逮捕和起诉重点。我们检查了在线警告信息是否会阻止个人访问声称几乎不包含合法色情内容的蜜罐网站。寻找该地点的参与者 ( n = 419) 被随机分配到五个条件之一；他们直接进入着陆页（控制；n = 100）或遇到警告信息，告知对观众的潜在伤害（n = 74）、对受害者的潜在伤害（n = 65）、警方追踪 IP 地址的能力（n= 81），或此类色情内容可能是非法的（n = 99）。我们测量了对网站的点击尝试。警告信息条件的流失率为 38% 至 52%，而对照组为 27%。最有效的信息是那些警告 IP 地址可以被追踪（赔率比 [OR] = 2.64）和色情内容可能是非法的（OR = 2.99）的信息。我们认为，警告信息提供了一种有价值且具有成本效益的策略，可以扩大规模以帮助减少在线 CSEM 的访问。
