And it could be a step forward. Randi Harper notes that sealioning is now against the rules, although I read it more as a rule against general obsessive behavior.
…well, let me quote the Twitter Rules directly:
If you send large numbers of unsolicited @replies or mentions;
Unsolicited replies or mentions, you say? Sounds a lot like the definition of sea-lioning. YMMV, but I recently had success in submitting a report about a user who had been almost exclusively tweeting about me for weeks. As far as I know, I’ve never once mentioned her, and I’ve had her blocked since the first time she popped into my notifications. She’s been subverting this block to screencap and discuss many of my tweets, consistently @mentioning me, and her followers would reply and include that @mention. This was a sustained campaign with no response, and I think that might be the the key. I asked in the report for the abuse team to consider all the tweets in her recent timeline, and they asked her to delete a good portion of them. It appears they targeted the tweets she issued where I was @mentioned. This is the first time I’ve heard of Twitter responding to context.
Oh, man, I read that and realized that there are a whole lot of people I never mention, but who have embarked on long term campaigns to yap ceaselessly at me and other people on FtB and Skepchick. They’re going to have to change their behavior now.
Well, that is, if Twitter actually enforces this new rule. I’m not confident that they will.
