I own a fairly large website & community back in the UK… It’s been running for about 18yrs now (114k users, nearly 500k threads)
People come & go, try to create a copy / steal users because they assume there’s $100,000’s to be made each year from advertising. There isn’t. Certainly not when you have fixed server costs and software licences.
Eventually they fizzle out, when they get bored or realise that the market isn’t big enough to suit. Each time they take a chunk of users and create badwill. We just ignore them now, and carry on regardless. We don’t even bother blocking URL’s now.
Annoyingly I reckon since the advent of FB, we took a 75% hit on user activity. Quite something for an uncatergorized, unorganized almost unsearchable resource!
Rise above, take the compliment that they’re imitating you & keep up the good work
