With the Internet - and online shopping/banking/business usage etc still set to grow exponentially for the forseable future the 'fight' for domain names is IMO going to get more competitive (read 'dirty' for that).
With football and fifa rule changes over the last 10 years you get a foul for virtually nothing these days. Norman Hunter would be sent off each match now. A red card was rare in those days. Now it's not thought about apart from the inconvenience of a 3 match ban.
Likewise, the number of DRS WILL increase, with the likelyhood, irrespective of rule changes, or maybe because of them, of more entries on the 3rule book for portfolio holders where there is no real pattern of abuse other than holding a portfolio of generic domains.
There should be careful though about interpretation and application of policy and procedure, especially rule 3. Automatic assumption of guilt will eventually lead to more antipathy to Nominet, and potentially a legal challenge to their authority to rule over this part of their current remit.
The 3 strikes rule should be raise to 5 within 2years and 3 within 1year within a rolling timescale. A bit like car insurance claims. Maybe generic domains should have a no-claims bonus?

Certainly possible within timescales of current registrant ownership and change of usage.
Out of date rulings should not be shown on the Nominet site, nor be applicable/useable within future DRS correspondance. A 'clean' driving licence if you will.
When the rule applies there should NOT be automatic assumption of guilt via rule 3. Any instance should be secondary to the evidence of the current case. Any expert with any legal/scientific background should start with that premise anyway. If they don't they should NOT be an expert.
Anyway, enough analogies.
