Social media marketing bots read pages for social scheduling, listening and app linking tools. Allow the tools your team uses and block the rest.
LINEOGPScraper identifies itself with this user agent string:
facebookexternalhit/1.1;line-poker/1.0Anyone can copy a user agent string. Transfon Security also checks where each request comes from, so a request that claims to be a known crawler but comes from the wrong network is treated as a fake, not as the real crawler.
We have not confirmed whether LINEOGPScraper follows robots.txt. Add a rule, then check your logs to see that it stopped. robots.txt is a plain text file at the root of your domain, such as https://example.com/robots.txt.
User-agent: line-poker Disallow: /
User-agent: line-poker Disallow: /private/ Disallow: /search
User-agent: line-poker Allow: /blog/ Disallow: /
User-agent: line-poker Allow: / User-agent: * Disallow: /
User-agent: line-poker group, LINEOGPScraper ignores your User-agent: * rules, so repeat any that should still apply.line-poker from LINEOGPScraper's user agent; check LINE's own documentation if it publishes a different robots.txt name.Treat robots.txt as a statement of your policy, and enforce it where requests arrive.
LINEOGPScraper fetches pages when your links are shared or syndicated. Keep it allowed so previews and feeds work, but leave it out of page views and ad requests.
Transfon Security for publishersWhen ads or posts are shared, LINEOGPScraper fetches the landing page. Those hits are not clicks, so keep them out of campaign reports.
Transfon Security for advertisersProduct links shared in chats and feeds are fetched by LINEOGPScraper. Keep it allowed so previews show the right image and price.
Transfon Security for e-commerceAllow LINEOGPScraper on public pages so shared links preview well, and keep it off the app.
Transfon Security for SaaS and APIsrobots.txt is a request, not an enforcement. Transfon Security shows LINEOGPScraper by name in the Top Bots report, so you can see how often it visits and which pages it reads. Block or allow it with a User Agent rule, or slow it down with a rate limit decision rule.

We have not confirmed whether LINEOGPScraper follows robots.txt. Add a robots.txt rule, then check your logs to see that it stopped, and block it by user agent if it did not.
Add "User-agent: line-poker" followed by "Disallow: /" to the robots.txt file at the root of your site. To enforce it, block requests whose user agent contains "line-poker" at your WAF. In Transfon Security that is one User Agent block rule.
No. robots.txt is voluntary, so LINEOGPScraper may not follow it, and anyone can send LINEOGPScraper's user agent, so a fake LINEOGPScraper ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.
