It seems that some journals are being considered spammers for linking to any sites outside of Livejournal, and being deleted.. So if this is all true, and will become a regular thing when someone links outside of the site, then I may consider putting a halt to cross-posting to Livejournal altogether. I’ll be keeping an eye on the comments over in that entry, so that I might see what develops. Currently, it's a wait and see/learn more situation.
Given that I link to things outside of Livejournal, it’s quite likely that I would be suspended for mistakenly being a spammer if an errant spambot script got hold of my journal; each cross-post is technically a link to outside of Livejournal, even if you don’t factor in linking to fanfic posted to Ao3 or wherever else I collect links from.
Kudos to meridian_rose for mentioning this, as it was the first I had heard of it.
I periodically import any comments from the Livejournal side (and now that the influx of new people importing has slowed a bit, it only takes about 5-20 minutes to complete an import as of this writing) so that nothing will be lost if my Livejournal happens to fall under some vague thing that all ends with a deletion, temporary or otherwise.
To those who prefer commenting on the LJ side: Should anything happen to my journal, you can easily find me and add me on Dreamwidth if you have an account there and haven’t already. Same username, even if you don’t have access to a cross-post link.
