I’ve been noticing an influx of users with anonomized usernames (ie: fjdasklfpudiosa722104891fdaf20j.srv.us).
As a moderator this concerns me because it immediately triggers a ‘this is a bot or nefarious actor’ instinct. Is there any reason not to be wary of these accounts?
That’s probably just mail that lands in your spam folder without being entirely blocked. According to Microsoft and Google approximately 99% of incoming spam (of the ~160 billion spam emails sent per day) never even reaches their users mailboxes. I assume that’s roughly standard across email providers. I am concerned comparably sophisticated filtering may become necessary on the Fediverse eventually.
My Google and Microsoft accounts are the only ones I ever get random spam on, tbh. I’ve never had any amount of unasked for mail with a paid provider or ISP’s email.
I get the concern but I don’t think you need to be as concerned as with email. Email is a lot simpler without a lot of validation. On the fediverse, HTTP Signatures are used to verify requests, so you can’t spoof stuff as easily.
That said, spam mitigation will probably still be an issue that continuously needs to be dealt with.
