I studied bot patterns on Reddit for a few years while using the site and was active in their takedown. My username is the same on there if you want to see the history of my involvement. What drove me to stop being so involved in bot takedowns is the extent to which Reddit as a site was continually redesigned to favor bots. In fact, I woke up today to a 3 day suspension for reporting a spam bot as a spam bot. I think what we need to examine in these cases, if possible, is if the bots were made strictly for the purpose of contesting blackouts (i.e. by Reddit themselves) or if they were made by a hobbyist or spammer. Given that these are on r/programming, that makes it seem more likely that a hobbyist programmer made these bots for a laugh or something, rather than it being an inside job. If the usual resources of Redditās API were accessible enough to provide a total history of these bot accountsā posts and comments, then that would help to clarify (this is what I mean about Reddit redesigns favoring bots). On the subject, I think Lemmy needs to start implementing preemptive anti-bot features while it is in an embryonic stage of becoming a large social media site (or a pseudo-social media site like Reddit) to future-proof its development
Iām very new to this site so Iām not sure what all already exists. Some features that come to mind based on my experience on Reddit and other sites:
Ability to search the entire site to see if a string of text (or multiple select strings of text) has already appeared there, including removed content. On Reddit, this was useful for seeing if an account has copied the comment, the text within a post, or the post title from elsewhere on the site. SocialGrep, Reveddit, and Unddit were my preferred sources of this info for Reddit. Text may also have been copied by a bot from other sites, but the original tends to be more accessible in those cases.
Ability to search the entire site to see if an image has already appeared there. This was essentially only relevant for repost bots and for bots that recognize an image from another post and re-comment from that other post. I do have concerns about this becoming relevant in the future for comments that contain images. TinEye and reverse image search on Google were my preferred sources of this info, but I donāt know if Lemmy posts will show up on those sites. u/RepostSleuthBot and the like were also helpful, especially if summonable in the comments.
Blocking users should only filter them from the blockerās feed, rather than make the blocked user unable to comment on the blockerās posts and comments. Spammers and scammers would abuse this system to prevent human users from calling them out on being spammers and scammers. While this design makes sense for sites based on personal profiles such as FaceBook or Twitter, it does not work for sites categorized by subject matter with impersonal user profiles.
Say what you will about the bad aspects of 4chan (and you should!), but the use of Captchas prior to publishing a post or comment seems to majorly mitigate bot activity.
This doesnāt seem to be a problem on Lemmy, but on Reddit, not all of the information of a spam report was sent to the subreddit mods. A report for Spam -> Harmful Bots would tell the admins that it was a Harmful Bots report, but the mods would only see it as a generic spam report and not be fully informed of the issue. Also, unbeknownst to mods, admins could link a subreddit rule report to a sitewide rule report. What I think Lemmy could improve on in this regard is to keep the openended custom report option, but also include pre-written report options for community rules, instance rules, and sitewide rules.
Some sort of indicator for groups of accounts which seem to be commenting only on the exact same posts as each other, which commonly are bots.
Entirely dependent on the subreddit or community, requiring some sort of verification post or other verification with a photograph of a paper with their username, the community name, and current date on it prior to permitting the user to post/comment may be beneficial.
A sitewide blacklist structured like r/BotDefense, wherein suspect accounts can be submitted and, if determined to be bot, will be automatically blacklisted from participating communities. Blacklist appeals will also be essential just due to human error.
As someone who had my 16+ year old account on Reddit permabanned for writing antibot scripts trying to keep the community I modded free from scammer and spammers, this is spot on.
