#科技资讯 Telegram 惊现公开群组聊天索引机器人，该机器人抓取高达 560 亿条用户发言数据，涉及 8.6 亿用户和 3600 万个订阅频道或群组。
目前机器人不提供特定用户的具体发言记录，但任意用户都可以查询他人的历史发言数据、加入 / 退出的群组、经常群里对话的好友、更名记录等等。

也有某些能利用的场景：
例如昨天本频道附属的讨论组有新用户加入，我用这个机器人查询了这个新用户，发现 TA 频繁更改用户名和 ID 并且加入了与 IT 完全无关的群组，所以我猜测这是发广告的，于是提前 BAN 了 TA。

The lead from Wall Street offers little clarity as the major averages opened lower on Friday and then bounced back and forth across the unchanged line, finally finishing mixed and little changed.The Dow added 33.18 points or 0.10 percent to finish at 34,798.00, while the NASDAQ eased 4.54 points or 0.03 percent to close at 15,047.70 and the S&P 500 rose 6.50 points or 0.15 percent to end at 4,455.48. For the week, the Dow rose 0.6 percent, the NASDAQ added 0.1 percent and the S&P gained 0.5 percent.The lackluster performance on Wall Street came on uncertainty about the outlook for the markets following recent volatility.
The Singapore stock market has alternated between positive and negative finishes through the last five trading days since the end of the two-day winning streak in which it had added more than a dozen points or 0.4 percent. The Straits Times Index now sits just above the 3,060-point plateau and it's likely to see a narrow trading range on Monday.
