It's nearer 95... Joined, spent 25 minutes following people, then left the building. Slightly odd behaviour I must admit.
If this had been from an IP in certain areas of the globe, I'd have been more worried, but Rotherham isn't noted for being the biggest SpamHaus on the planet.
@giffyyy - you do realise this isn't facebook, and to interact you don't just "follow" hundreds of people like some creepy stalker...
as to "can I block?" - I can't see that option (but it may be that as staff I'm not allowed to block people - we get strange permissions like that) what you can do is put them on ignore - in your profile, click on their icon and select Ignore.
