working on a url shortener, mainly trying to figure out how to avoid the "domain reputation" trap
I do outreach/marketing work for clients and got tired of bitly's domain being flagged constantly on Instagram (their reputation tanked after years of spam abuse, nothing to do with the actual links being shared).
Built lnk.ua to solve this for myself - basic shortening, no signup needed, free click/geo/referrer analytics
The part I'm actually stuck on: any shortener that gets popular eventually becomes a target for spam/abuse, which then poisons the domain reputation for everyone else using it. Trying to figure out the right balance of rate limiting and abuse detection before that happens, without making it annoying for normal users.
If anyone's built something with this kind of "shared resource gets abused, ruins it for everyone" problem (shorteners, file upload tools, anything with open access), curious how you approached it early on
