掠夺性期刊的问题不只是钱——几千美元的 APC 打了水漂是小事，论文发在一本检索不到、学界不认的刊上，那篇工作基本就废了，而且撤不回来。 判别不能靠「我听说过这本」：印象既覆盖不全也会过时。这里直接查三个公开注册库——ISSN 官方注册库（这个号是不是真的）、DOAJ（开放获取期刊的主要白名单）、Crossref（有没有注册 DOI、近年发文量有没有异常暴涨）。红旗只按客观事实给，每一条你都能自己复核。 再加上四件必须自己确认的事，其中「随便挑两个编委去他们机构官网核对」这一条最有用——盗用学者姓名是这类期刊的常规操作，而被盗用的人往往并不知情。$2 解锁批量核验、约稿邮件的话术拆解、以及已经投出去或已经付款之后的处理路径。The cost of a predatory journal isn't mainly the APC. Publishing in a venue that isn't indexed and isn't recognised effectively wastes the work — and you generally can't take it back. Recognising them can't rest on whether you've heard of the title. This checks three public registries directly: the official ISSN register (is the number real), DOAJ (the main whitelist for open-access journals), and Crossref (are DOIs registered, and has annual output spiked implausibly). Red flags are raised only from verifiable facts you can re-check yourself. Plus four things to confirm before paying — of which "pick two editorial board members and check their own institutional pages" is the most useful, because listing scholars without their knowledge is standard practice. $2 unlocks batch checking, a breakdown of solicitation-email tactics, and what to do if you've already submitted or already paid.
一次核验多本备选刊并排出对比表 + 约稿邮件的话术逐句拆解（哪几句是模板、哪几句在制造紧迫）+ 已投稿但还没交钱怎么撤 + 已经付款或已发表的补救路径 + 选刊时该看的正经指标。Check several candidate journals at once with a comparison table, a line-by-line breakdown of solicitation-email tactics, how to withdraw before paying, what can be done after payment or publication, and the legitimate signals to select on instead.
本工具只做公开注册库的检索与基于客观事实的提示，不对任何期刊或出版商作出「是否掠夺性」的判定，也不构成学术或投稿建议。未被 DOAJ 收录不等于有问题（大量正规订阅制期刊本就不在其中）；被收录也不代表质量保证。检索结果可能滞后或不完整。最终判断请结合你所在机构认可的期刊目录、导师与同行意见，以及你自己对该刊近期文章的阅读。你填写的内容不入库。This performs public-registry lookups and raises fact-based notes. It does not classify any journal or publisher as predatory and is not academic or submission advice. Absence from DOAJ does not imply a problem — many legitimate subscription journals are not listed — and inclusion is not a quality guarantee. Registry data may lag or be incomplete. Rely also on your institution's recognised list, your supervisor and colleagues, and your own reading of the journal's recent articles. Nothing you enter is stored.
