Python 2.7 对于appengine应用程序中过度使用的URL，我能做些什么？

我的appengine应用程序（一个分类广告网络应用程序）通过许多不同的IP号码收到许多请求（当前323.2个请求/分钟），这些请求都来自我现在删除的相同URL:s。最好阻止IP号码，但它们通常是不同的IP号码

它返回一个404，IP号码通常不同，但当我搜索其中一个IP号码时，它被报告为“坏IP”，并且在中国

302看起来像这样，我要修正它，让它返回404

该类如下所示，我将进行更改，以便在删除内容时返回404

class Recommend(Base2Handler):
    csrf_protect = False

    def post(self, key):
        ad = db.get(db.Key(key))
        email = self.request.POST['tip_email']
        msg = unicode(self.request.POST['tip_msg'])
        if isinstance(msg, unicode):
            msg = msg.encode('utf-8')
        name = self.request.POST['tip_name']
        if isinstance(name, unicode):
            name = name.encode('utf-8')
        title = ad.title
        if isinstance(title, unicode):
            title = title.encode('utf-8')
        host = self.request.host
        senderemail = \
            (users.get_current_user().email() if users.get_current_user() else ('info@montao.com.br'
                                                                                if host.endswith('.br'
            ) else 'Kool Business <info@koolbusiness.com>'))
        recommends = _('has recommended')
        message = mail.EmailMessage(sender=senderemail,
                                    subject='%s %s %s' % (name,
                                                          recommends, title))
        message.to = email
        message.body = '%s %s/vi/%s.html' % (msg, host, ad.key().id())
        message.send()
        matched_images = ad.matched_images
        count = matched_images.count()
        if ad.text:
            p = re.compile(r'(www[^ ]*|http://[^ ]*)')
            text = p.sub(r'<a href="http://\1" rel="nofollow">\1</a>',
                         ad.text.replace('http://', ''))
        else:
            text = None
        #self.response.out.write('Message sent<br>')
        self.redirect('/vi/%d.html?msgid=msg_sent' % (ad.key().id(), ))

还有什么我能做的吗？模型如下所示

    cities = db.ListProperty(db.Key)

打开csrf\u protect肯定会有所帮助。当他们看到自己的帖子没有被处理时，他们会很快放弃

现在，他们可能正试图用暴力在你的网站上发布垃圾邮件
